Restricted Substances Test Platforms.

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.

Protheragen-ING is committed to helping you ensure the safety and compliance of your cosmetics. Please contact us today to discuss your specific testing needs. We will respond within 2-4 working days.
