Preservative Analyzer provides a photo diode array detector to give reproducible and reliable chromatography with excellent peak shape ad accurate qualitative analysis to check the exact spectrum.
Methylparaben and Phenoxyethanol are very commonly used as preservatives for cosmetics, drugs and other skincare products but they are strictly regulated because their overuse can cause toxicity at higher concentration to human body.
For they have an absorbance at UV/Vis wavelength range, these are usually analyzed by HPLC after extracted by organic solvents such as Methanol or DMF.
For the maximum absorption wavelength(λ max) differs depending on components, (Methylparaben : 257 nm, Phenoxylethanol : 271 nm), one of peaks could be resulted with low sensitivity.
Getting rid of this possibility, Our preservative Analyzer provides a photo diode array detector to give reproducible and reliable chromatography with excellent peak shape ad accurate qualitative analysis to check the exact spectrum.
Easy of use with sophisticated CDS (Chromatography Data System)
No interference in compounds with same retention time
Accurate and efficient sample preparation method
Simple start-up manual and method setup support
Low maintenance cost and long term stability
