The Techniques of Thin Layer Chromatography and the Study of Carbohydrates Using Thin Layer Chromatography [PDF]

open access: yes, 1977
Refined Kraft pulp is found to contain D (+), Mannose, D (+) Xylose, and Glucose; and not to contain Galactose. Silia gel plates and Kieselguhr plates were used for the separation.

An integrated targeted and untargeted approach for the analysis of ergot alkaloids in cereals using UHPLC - hybrid quadrupole time-of-flight mass spectrometry [PDF]

open access: yes, 2015
An ultra-high performance liquid chromatography hybrid quadrupole time of flight (Q-TOF) mass spectrometry (MS) method is described for the simultaneous quantitative determination of common ergot alkaloids and the screening, detection and identification ...

Determination of Cyanogenic Compounds in Edible Plants by Ion Chromatography

open access: yesToxicological Research, 2013
Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections.

Pitfall in the high-throughput quantification of whole blood cyclosporin A using liquid chromatography-tandem mass spectrometry [PDF]

open access: yes, 2005
In a growing number of laboratories the technique of liquid chromatography-tandem mass spectrometry is used for the quantification of cyclosporin A in whole blood, employing cyclosporin D as the internal standard. Cyclosporin A is extensively metabolized

Effects of filtration sterilization on the stability of ketamine, selected benzodiazepines and metabolites in female urine [PDF]

open access: yes, 2017
Benzodiazepines (Benzos) and ketamine (K) are compounds that have been encountered in Drug-Facilitated Sexual Assault (DFSA) cases. Due to the intimate nature of these crimes, evidence collection is often postponed due to delays and/or reluctance in ...

Influence of the sebaceous gland density on the stratum corneum lipidome [PDF]

open access: yes, 2018
The skin surface lipids (SSL) result from the blending of sebaceous and epidermal lipids, which derive from the sebaceous gland (SG) secretion and the permeability barrier of the stratum corneum (SC), respectively.

Online Parallel Accumulation–Serial Fragmentation (PASEF) with a Novel Trapped Ion Mobility Mass Spectrometer

open access: yesMolecular & Cellular Proteomics, 2018
PASEF multiplies the sequencing speed without any loss in sensitivity and is implemented in the timsTOF Pro instrument introduced here. Sequencing speeds above 100 Hz enable single run proteome analysis at a depth of 6000 proteins, making the instrument ...
