GERSTEL was pleased to host users of Agilent Technologies’ UHPLC instrumentation for a Master Class training session.
Not all GC/MS analyses require a solvent to be successful. Come hear from leaders in the field how you can reduce or eliminate the use of solvents in your work. Solventless Sample Preparation Techniques for Mass Spectrometric Analysis PittCon 2015 – New Orleans, Louisiana
When people talk about Thermal Desorption (TD), GCMS, and the software for both, the word ‘integration’ and/or ‘easy to use’ or something like that often comes up in regards to the TD system software.
To date, sample preparation of solid materials requiring ultrasonic extraction has mostly been performed manually. This is in part due to the fact that automation of the sonication step has not previously been available; however, another reason is that the solid particulate can create a suspension in the extraction solvent, which can easily block a syringe, making automated collection of the extract and subsequent injection to the GC or LC unreliable.
The analysis of airborne aldehydes and ketones first involves collection of the analytes by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH).
The determination of opioids, cocaine, and metabolites from blood serum is a routine task in forensic laboratories. Typical methods include many manual or semi-automated steps like protein precipitation, dilution, solid phase extraction, evaporation, and derivatization preced¬ing GC/MS or LC/MS analysis.
The latest issue of GERSTEL Solutions Worldwide in now aviable for viewing on our web site. This issue focuses on intelligently automated sample preparation, material analysis of amber, analysis of adhesives and polymers, clinical chemistry and wine analysis for the determination of flavor components.
GERSTEL will be sponsoring and attending at the 3rd Stir Bar Sorptive Extraction Technical Meeting. The meeting will be held January 26th thought the 27th at Novotel Paris Charenton, France.
The determination of aroma compounds in edible oils is important for manufacturers and vendors of these products. Off-flavors derived from unsaturated fatty acid degradation are of interest.
The clearance of drugs, toxins, environmental contaminants and other waste products from the body often involves processing in the liver to form glucuronide conjugates, which are more readily solubilized and excreted by the kidneys.
