  Publication date: Available online 14 September 2013 Source:Organic Geochemistry Author(s): Daniel B. Nelson , Julian P. Sachs Three methods are presented on how to purify acetylated sterols, acetylated triterpenols and individual alkenones for hydrogen isotope analysis from marine and lacus more

• A Capillary Fraction Collector Coupled to a Fluorescence Reader: A Novel Device to Continuously Quantify Glutamate During Microdialysis

  Microdialysis coupled to HPLC is the preferred method for quantification of glutamate (Glu) concentrations, both in normal and pathological conditions. However, HPLC is a time consuming technique that suffers from poor temporal resolution. Here we describe an alternative method to measure glutamate more

• One‐step multiple component isolation from the oil of Crinitaria tatarica (Less.) Sojak by preparative capillary gas chromatography with characterization by spectroscopic and s ...

  Gas chromatographic analysis revealed that the oil of Crinitaria tatarica was rich in sabinene (32.1%), β‐pinene (8.8%), and two unknown (M+200) compounds (I) and (II) (21.4% and 3.4%). One‐step multiple fractionation of the oil and separation of two unknown constituents were performed using prepa more
