COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
method was developed using ultra-high performance liquid chromatography with diode array detector (DAD). Furthermore, selection of orthogonal wavelengths was made to extract maximum information from the ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
American Herbal Pharmacopoeia) was developed using ultra high performance liquid chromatography coupled with a diode array detector. Next, a correlation analysis comparing the wavelengths was performed and ...
CHROMATOGRAPHIC FINGERPRINT DEVELOPMENT FOR THE DETECTION OF TRIBULUS TERRESTRIS IN PLANT FOOD SUPPLEMENTS
Liquid Chro-matography- Diode-Array detector (UHPLC – DAD) and evaluated the presence of TT in 20 unknown illegal plant food supplements by using the developed fingerprinting method. Method: UHPLC- DAD was ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS

DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS
A liquid-liquid extraction was used as a sample ‘clean-up’ for lubricants. The sample was then injected using gas chromatography-flame ionization-mass spectrometry (GC- FID- MS). The AHP s were analyzed using a HS- ...
Study of the possible migration risks of food contact materials for children under 3 years
