Advanced Testing Technology

DEG testing typically involves a combination of qualitative and quantitative analysis to detect and measure the presence of DEGs in cosmetic samples.

Below are some common test methods and procedures for our DEG testing.

Gas Chromatography (GC)

It involves separating and quantifying the individual components of a sample based on its volatility. In GC analysis, the sample is evaporated and injected into a gas chromatograph equipped with a suitable detector, such as a hydrogen flame ionization detector (FID) or a mass spectrometer (MS). Retention times and peak areas of DEG compounds were measured and compared with known quantitative standards.

High-Performance Liquid Chromatography (HPLC)/Ultra-Performance Liquid Chromatography (UHPLC)

In this method, the sample is dissolved in a suitable solvent and injected into the liquid chromatograph.

We use a stationary phase to separate the DEGs from other components in the sample and a mobile phase for elution. Detection can be performed using various detectors, such as UV-visible detectors or refractive index detectors.

Mass Spectrometry (MS)

Mass spectrometry can be combined with gas or liquid chromatography for DEG analysis. It involves ionizing sample molecules and measuring the mass-to-charge ratio of the resulting ions.

The characteristic mass spectrum of a DEG can be compared to a reference spectrum for identification, and the intensity of specific ions can be used for quantification.

Spectrophotometry

Spectrophotometry is a technique that measures the absorption or transmission of light at specific wavelengths by a sample. DEGs can be quantified indirectly by reacting with appropriate reagents to produce colored compounds and measuring the absorbance of the colored products using a spectrophotometer. This method requires the use of specific reagents and following an established protocol.
