Is Inert Waste Dangerous

This type of waste does not pose a threat to the environment, animals or human health and will not affect the quality of water sources it may be in contact with.

The main issue inert waste poses to individuals and businesses is what to do with. Because it does not decompose , it can become problematic as it takes up a lot of space.

Workplace Uses Of Inert Gases

Inert gases are used in workplaces for a number of purposes. Many of these uses are not focused on safety however, they are also used as an important safety tool, such as in the fire suppression systems discussed above.

Uses of inert gases that arent focused on safety include their use as a compressed gas. Numerous industries use inert compressed gases to operate specific pieces of industrial equipment, such as those that rely on pneumatic tools. While these uses arent explicitly safety focused, the use of an inert gas is often preferable, as it eliminates any danger that the gas will react if introduced into a potentially hazardous setting.

The use of compressed inert gases is not 100% safe. The primary danger associated with the use of a compressed inert gas is the danger of the gas tank or cylinder rupturing violently, which could potentially cause it to explode due to the sudden pressure release.

Certain types of welding and chemical process activities also use inert gases as shields to prevent unwanted chemical reactions. For example, metal inert gas welding is a type of arc welding that uses inert gas as a shielding gas to prevent airborne contaminants from affecting the welding process. Argon and helium are the most common gases used for this purpose.

Coating Properties That Will Improve Instrument Flow Paths

Simple corrosion resistance is important but there are other factors to consider when considering a coating to be used in bio analysis. Some examples of factors to consider are:

  • Anti-stick
  • Oleophobicity

Dursan® meets all the criteria and is NSF and FDA compliant making it worth consideration when selecting a bio-inert material.

NSF approved and FDA Compliant

Our Dursan® coating is compliant with NSF/ANSI 51 and all applicable requirements. That means that it is safe for food contact and also meets the FDAs requirements for compliance. FDA regulates coatings via the Code of Federal Regulations , specifically 21 CFR 175.300 which lists what raw materials are acceptable and unacceptable for the formulation of coatings.

According to the FDA, a coating must:

1. Pass the solvent extraction tests listed in 21 CFR 175.300.

2. Contain no heavy metals.

3. All coating components must conform to the materials listed by the FDA in order to be compliant.

These stipulations are also required for NSF/ANSI 51 certification. Dursan® successfully meets these requirements.

Influence Of The Underlying Surface Chemistry And Immobilized Proteins On Endothelial Cells


As depicted above, the possibilities for further modification of the terminal group of the attached silane are enormous. Therefore, an attachment to many other cell types besides osteoblasts might be feasible by a careful pairing of an immobilized ligand on a surface with a specific receptor of the desired cell. As endothelial cells are necessary components of almost any kind of tissue integration, due to their involvement in the tissues vascular supply, their potential immobilization on an implant surface utilizing a SAM-transferable technique shall be discussed in more detail.

When the underlying chemistry is defined and properly selected, the next step is to incorporate cell attachment proteins to further enhance the affinity between cell and surface. Here, a protein-specific adsorption to the surface might promote not only adhesion but proliferation and cell production as well. In 2002, Balcells and Edelmann investigated the potential of pre-adsorbed fibronectin, laminin and gelatin to stimulate these impacts on bovine aortic endothelial cells . The results of their experiments showed, as expected, that these mediators do indeed stimulate BAEC responses differently, depending on the kind of immobilized protein, as long as the cell-site binding specific 5 integrin was not blocked. Although their experiments were performed on tissue culture polystyrene , the results should be applicable to other surfaces, such as SAMs, with conjugated proteins as well.

Safeopedia Explains Inert Gas

The term inert gas is somewhat of a misnomer, as these gases can, in fact, be reactive under certain conditions. As such, in the context of chemistry and materials science, these gases are generally referred to as noble gases. The term noble has historically been used in chemistry to describe the reluctance of certain metals to react chemically, and the term noble gas is used to connote that same reluctance.

Biological Interaction On The Functionalized Sam

As depicted above, recent advances and breakthroughs in the SAM-on-ceramics topic shifts attention towards the coupling of biomolecules and related proteins onto the terminal layer end for a promoted tissue-conduction as well as tissue-integration in general, and in terms of orthopaedics towards a specific osseointegration. Therefore a broad overview of the underlying mechanisms in osteoblast cell adhesion and differentiation in contact to biomaterials shall be given here.

Key Factors To Consider When Selecting A Coating For Bio

Stainless steel, a common medical diagnostic flow path material, is an active surface that can cause protein retention, chemical adsorption and is susceptible to corrosion when bleach or acids are used as a cleaning or rinse agent. Thats why various types of coatings have been used to improve the surface properties of medical diagnostic instruments for decades, but few have been completely successful in reducing protein retention and carryover. Get our latest e-book on bio inert coatings.

Instrument manufacturers have gone to great lengths to evaluate alternative materials to solve non-specific protein binding, protein carryover, fouling and rust problems. Unfortunately, commonly used fluoroploymers, like AF1600, are not acceptable in high durability applications. Small bore surfaces like needles, valves, or fittings are also challenging for polymer-based or other line-of-sight surface treatments. To address durability and form factor concerns, manufacturers take into account several key factors when selecting bio-inert materials.

Factors to consider when selecting bio-inert materials:

  • Improved analytical sensitivity, eliminating interaction with flow path surfaces
  • Prevents non-specific protein binding for many target proteins, preventing false positive results
  • Corrosion resistant and durable
  • Able to be applied to surfaces without changing part tolerance or performance
  • Meets FDA regulatory compliance for coatings

Corrosion Resistance And Durability

A bio-inert sampling flow path is critical for achieving consistent bio separations in medical diagnostics and HPLC analysis. Over time inert surfaces degrade and test flow paths corrode due to frequent rinse cycles from aggressive chemicals like bleach. The corroded and pitted surfaces are perfect hiding places for sticky compounds and bio growth, making carryover and contamination a real concern. We tested Dursan vs. a common stainless steel coating to evaluate the corrosion resistance when exposed to bleach. After immersion in 15% bleach for 24 hours we found the Dursan coated surface outperformed most coatings and exhibited impressive corrosion resistance.

What Is Inert Pair Effect Explain With Example

Inert pair effect is defined as. The non-participation of the two s electrons in bonding due to the high energy needed for unpairing them. The inert pair theory was proposed by Sidgwick. He along with Powell accounted for the shapes of several molecules and correlated the shapes with some of their physical properties.

Chemical Activation Of Inert Ceramic Surfaces

Chemical Equilibrium: Effect of an Inert

As described above, high-strength medical-grade ceramics are bioinert, yet possess unique material properties which make them excellent implants for various medical applications. An activated surface, without the supplement of an additionally engulfing material, would therefore greatly increase the ceramics applicability and deployment areas. As shown previously, the desired bioactivation can be achieved by activation of the surface alone, without alteration of the underlying substrate. Therefore, several investigations into possible modification strategies were undertaken over the last couple of years. This chapter is aiming to give a general overview over the early stages of research so far. Furthermore, a more in-depth discussion of the most recent, although quite limited, results from the newly surfacing strategy using SAMs as a multi-purpose layer for subsequent biological activation is given, along with a brief introduction into the relevant portions of the SAM research thus far.

Definition Of Bioactive Materials

Bioactive materials represent a new generation of biomaterials, which are different from the traditional bio-inert biomaterials. Traditionally, a

biomaterial is considered to be a non-viable material used in a medical device intended to interact with biological systems. Biomaterials may be distinguished from other materials in that they possess a combination of properties, including chemical, mechanical, physical, and biological properties that render them suitable for safe, effective and reliable use within a physiological environment .

However, by 1999, a biomaterial was defined as âa material intended to interface with biological systems to evaluate, treat, augment, or replace any tissue, organ, or function of the bodyâ . This shows there is an increasing trend for a biomaterial to shift from a traditional bioinert material to a bioactive material.

Direct Surface Modification On Ceramic Substrates

In 2005, Fischer et al. reported the successful direct binding of hydroxyl functional groups onto alumina substrates without an attached silane carbon chain. After 24 h immersion in a bath of 1 M NaOH at 100 °C, the aluminium oxide exposed at the surface was modified to aluminium hydroxide , according to the following reaction:

In 2007, Kaltenborn et al. reported the successful coupling of phosphate groups to properly sintered and subsequently grinded and polished alumina samples. A precipitation of calcium phosphate after SBF tests suggests a bioactive layer, which may be expanded to a coupling method for amino acid sequences of proteins. However, the treatment necessary to bind the phosphate groups was extremely aggressive, as the sample was boiled in monoaluminiumphosphate solution at pH 1. SEM studies have subsequently shown a micro-porous surface structure, indicating an erosion process during treatment. Although mechanical tests were not performed, a deterioration of mechanical key properties is likely. On the other hand, a porous surface might promote bone ingrowth and therefore add to the bonding process, a feature that requires additional attention when investigating highly aggressive surface treatments.

Biologic contamination can have a negative impact on a wide range of industries and applications including medical diagnostics, oil and gas production, refining, chemical process, semiconductor, waste water, cooling water and physical plant systems. Bio-activity not only disrupts test results in medical diagnostics and HPLC analysis, a bio active environment can cause corrosion in plant systems, degrade oil and gas feedstock quality and foul wastewater and cooling water systems. Bio contamination can cause real damage to the bottom line. That’s why it’s important to test for and control biological contamination, and why selecting a bio-inert surface is an important factor to consider when designing a sample transport system. A bio-inert surface assures adequate detection and selectivity is achieved when testing for biologics.
