Measurement of acetic acid vapor in the workplace using passive sampling SPME and on-fiber derivatization with 1-pyrenyldiazomethane: Comparison with active sampling.
HPTLC–MS analysis of quinine in tonic water and caffeine in coffee and cola drinks. Tonic and cola drinks decarbonized through ultrasonication, and coffee extracted through PTFE filter.
Straightforward HPTLC-MS analysis of lactose in dairy products (milk or yoghurt) using only protein crash, centrifugation and dilution as sample preparation.
Here we show how LC and MS methods may be optimized using a non-toxic surrogate of the ADC, an “ADC-mimic”, that behaves very similarly to the Cys-linked ADC Adcetris (Seattle Genetics).
Volatile organic compounds are trapped by adsorption and recovered by thermal desorption, analysis is performed by capillary gas chromatography and FID or MS detection.
This report demonstrates the potential of solid phase microextraction as a clinical research tool for the extraction of VOCs associated with lung cancer from human breath.
We describe here a rapid and sensitive method to separate and measure D-2-OHG and L-2-OHG enantiomers using high-resolution mass spectrometry (HRMS) detection.
In this study, we investigated the effect of adding Tween® 20 and Tween 80 on the elution of proprietary mAb 221 under size exclusion chromatography conditions.
