Additive & Preservative Analysis

Additives and preservatives are widely added to foods, medicines, cosmetics and other kinds of materials in our life. However, many studies have shown that adding too much preservative or additives to materials will influence the characteristics of the materials or cause potential harm to people who get in touch with it. There are numerous restrictions regarding the maximum allowance of preservatives and additives in various fields, so food preservatives and additives detection is of great significance. Alfa Chemistry offers validated preservative or additives analysis to help keep the preservative or additives contents away from the top ceiling and prevent people from being harmed.

Alfa Chemistry provides professional and detailed analysis results through the following primary equipment.

• Thin-layer analyzers

Thin-layer analyzers make good use of digital technology to accurately reflect information (qualitative and quantitative) in thin-layer chromatography. TLC can be observed online with instant photo, instant preservation, and real-time quantitative analysis, reporting a variety of quantitative data.

• Gas chromatography-mass spectrometry

Gas chromatography has a strong ability to separate; mass spectrometry has unique identification capabilities for unknown compounds, and it is extremely sensitive, so GC-MS is one of the most powerful tools for the separation and detection of complex compounds.

• High performance liquid chromatography

It is suitable for liquid samples and not limited by the volatility of the sample. HPLC has the advantages of high resolution, high sensitivity, high speed, repeated use of the column, and easy extraction of eluted components.

Utilizing these techniques, we can separate, identify and quantify the preservatives or additive added to the material. More importantly, we will provide professional analysis reports and have effective communications about the resulting data with you. Contact Alfa Chemistry for preservatives or additives analysis services, and you'll be connected to a team of dedicated staff to help your product to meet all regulatory requirements. All analytical process documentation and raw data will be delivered with a clear report that allows you to see the full results of our testing.
