Test Platforms

Liquid Chromatography

Liquid chromatography has been widely used for the detection of organics in cosmetics because of its wide detection range, high separation efficiency and strong automation.

Liquid-Mass Spectrometry

Liquid Chromatography-Mass Spectrometry (LC-MS) has the ability to resist contamination and has excellent sensitivity and selectivity, which enables the detection of hormones, antibiotics, pollutants and other allergens in cosmetics.

Gas Chromatography

Gas Chromatography/Triple Quadrupole (GC/QQQ) provides a powerful tool for cosmetic testing with excellent sensitivity, ultra-fast scanning speed, and easy MS/MS functionality to meet the most demanding qualitative and quantitative analysis requirements.

Atomic Spectroscopy

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is increasingly becoming the best choice for elemental analysis in cosmetics due to its high sensitivity, low detection limit, low interference, rapid multi-element simultaneous detection, and qualitative and semi-quantitative features.
