The manufacturing industry widely uses solvents. Solvents play a role at many different stages in the manufacturing process from cleaning assembly line equipment to engineering pharmaceutical products. Yet, if they are not properly removed, residual solvents can negotiate the quality or safety of a product. Taking pro of residual solvent testing GC is a way to combat potential quality issues and ensure a safe product.

Let us first understand the term solvent?

The solvent is a gas or liquid that dissolves or extracts other substances. Some of the most collective solvents used in manufacturing include butane, ethanol, propane, hexane, and acetone. These solvents can be used to dissolve greases and oils, clean electronics and tools, or mix or thin pigments. Solvents are also very imperative for the creation of medicines or drugs and other pharmaceutical products. For samples, solvents are frequently used at the starting of the manufacturing process to create the active ingredients for ointments and other topical products.

Now know the term residual solvent?

The residual solvents are solvents that are used in the manufacturing of things that are not completely removed after processing. From time to time solvents are a critical part of the actual face paint of the product. For instance, solvents can be used in glue and adhesive manufacturing to control the drying properties.

Still, there are guiding principles for the number of residual solvents that can be left behind and still be considered safe. At unsafe levels, they can either be harmful to the environment or humans. Additionally, residual solvents can also compromise the worth and/or functionality of the product. For instance, removing cleaning solvents is essential during the processing of a circuit board. If (Marijuana testing) residual solvent is present, the conformal coating and/or solder mask will not adhere properly to the circuit board.

What do you mean by residual solvent testing?

Residual solvents, or other impurities, all are determined in residual solvent testing and if they’re present in harmful amounts. Nit just this, though, it can also determine whether the proper solvent purging process was followed during product development.

Pros of residual solvent testing…

This testing is a way to ensure product quality and safety.For instance, ethanol and other solvents are often used in the production of drugs or other pharmaceutical products. Since medicinal products are ingested or implanted in the body, residual solvent testing and Marijuana testing is critical to ensure that solvents are not present at health-threatening levels.

Residual solvents are also frequently used in the production of plastic packaging for various food products. If so much of the solvent is retained in the packaging, it could give off an unpleasant odor or spoil the taste of the food. Residual solvent testing can quantify the level of residual solvents and determine if they will cause odor or taste issues.

What techniques are used?

In residual solvent testing commonly used headspace GC/MS technique. Gas chromatography-mass spectrometry identifies the precise composition of a sample. Throughout this process, the sample is injected into a gas chromatograph to volatilize the sample and separate the various components. The removed components then go into a mass selective detector to identify how much of each element is present.

Headspace analysis is conducted in tandem with GC/MS analysis. This procedure analyzes the volatile and semi-volatile organic compounds given off by a sample during heating or over time. Immobile headspace analysis is ideal for analyzing residual compounds.

Conclusion

This can identify and quantify which residual solvents are present in a sample. Manufacturers will be able to trace the issue to a step in the manufacturing process and make the necessary adjustments, only if high levels of residual solvents are found.

Description: Residual solvent testing is a necessity for any organization that uses solvents in manufacturing and assembly processes. Residual solvent testing is a way to dodge contamination and product failures and ensure that your product is safe for human use.
