  • Enhanced Purification of Capsaicins with the CombiFlash® EZ Prep

    Abstract In this application note, capsaicins are used as a model for compounds difficult to resolve with flash chromatography. Capsaicin compounds possess very similar structures making them difficult to resolve from each other. Although these compounds can be resolved on flash chromatography columns, such as the RediSep® Rf Gold C18, preparative high pressure liquid chromatography ...

  • Gas chromatography - What are Columns?

    Liquid and gas chromatography instruments wouldn't work without columns. Both liquid and gas chromatography analyze samples by separating them into their individual chemical components. A column, a long tube lined with specialized chemicals, is required for this process as it forms part of the instrument which performs the separation. When a sample makes its way through the tube, certain ...

  • Solaris - What`s in a name?

    A lot of thought goes into naming Peak Scientific products. Today we are sharing the meaning behind the name of our Solaris 10 nitrogen generator. Peak's Solaris 10 nitrogen generator for ELSD is engineered to meet the nitrogen requirements for high performance liquid chromatography (HPLC) with evaporative light scattering detectors (ELSD) and compact mass spectrometers. Designed primarily ...

  • Chromatography explains why luminous fungi glow in the dark

    When you think of organisms that glow in the dark you might think of jellyfish or fireflies, but some mushrooms glow after dark too, and now we know how. ...

  • UCT XtrackT® Sorbent Cited in Drugs in Wastewater Article

    Environmental analysts are often tasked with the evaluation of illicit and prescription drugs in wastewater samples in an attempt to better understand the epidemiology of a populated area. Due to the challenging consistency of this matrix, clean-up is often vital in order to achieve accurate detection. In a recent paper authored by Richard Bade et al., published in Analytical and ...

  • What is a Syringe Pump?

    A syringe pump is a type of infusion pump originally developed to help administer drugs to patients in a controlled manner. Early attempts to construct infusion pumps were made in the 19th century. However, the first infusion device was introduced in the 1950s to be used in chemotherapy. In the 1970s, the development of ambulatory infusion technology enabled the pumps to be used in research; ...

  • Identification and risk assessment of human and veterinary antibiotics in the wastewater treatment plants and the adjacent sea in Tunisia

    In the following study, we came up with and validated a prompt, sensitive and precise method for the simultaneous determination of 56 antimicrobial drugs (tetracyclines, sulfonamides, β-lactams, macrolides and quinolones) using the ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). This method was implemented with success to determine antibiotics in samples ...

  • Sources of pharmaceuticals and personal care products in swimming pools

    Pharmaceuticals and personal care products (PPCPs) in swimming pool water are hypothesized to originate from fill water and anthropogenic sources like urine, sweat, swimwear and body surfaces. However, research exploring PPCP origins in pools is lacking. This research investigates PPCP sources at 31 swimming pools. Pool water was analyzed for 24 representative PPCPs using advanced liquid ...
