Thirteen samples of authentic absinthe dating from the preban era (i.e., prior to 1915) were analyzed for parameters that were hypothesized as contributing to the toxicity of the spirit, including naturally occurring herbal essences (thujone, pinocamphone, fenchone), methanol, higher alcohols, copper, and antimony. The total thujone content of preban absinthe was found to range between 0.5 and

High-performance liquid chromatography (sometimes referred to as high-pressure liquid chromatography) is a chromatographic technique used to separate a mixture of compounds in analytical chemistry
The functional detection of novel enzymes other than hydrolases from metagenomes is limited since only a very few reliable screening procedures are available that allow the rapid screening of large clone libraries. For the discovery of flavonoid-modifying enzymes in genome and metagenome clone libraries, we have developed a new screening system based on high-performance thin-layer
The extracted samples were centrifuged at 10,000 × g at 4°C for 5 min, and the supernatant was stored as 1.0 ml samples collected in 20 ml glass vials at −80°C until measurement. 1-Propanol at a final concentration of 100 ppm was included as internal standard prior to analysis.
I am looking for extra small vials for HPLC. Standard vials with inserts have usually a volume of 150 or 200 microliter and a minimum volume of 10 microliters.
High Performance Liquid Chromatography (HPLC) is frequently used in diverse chemistry disciplines to separate, identify, and quantify compounds. Over the years, HPLC has played an essential role in laboratories worldwide. Since the early emergence of HPLC around 1970 [1,2] countless improvements and
The residues were collected in 2 ml methanol, filtered (cellulose acetate, 0.45 lm) and stored in brown glass HPLC-vials at 2°C until analysis. Quantitative determination of ergosterol was conducted by reversed-phase HPLC; 20 μl of the extracts were injected by an HPLC autosampler (Beckmann Coulter, System Gold 125 Solvent Module) into a
The frozen tissue was crushed with a glass rod, the bottom of the tubes pin-pricked, set inside another 1.5 mL tube and centrifuged in a refrigerated centrifuge (Sigma Laboratory Centrifuges, Osterode am Harz, Germany) at 5 °C at 10,000 rpm for 4 min.
