  • Sampling of Carbonyls Using a Dual-Layer LpDNPH Glass Sampling Tube and HPLC Analysis

    The dual-layer LpDNPH sorbent tube is an air sampling device designed for sampling carbonyls (e.g. formaldehyde) in ambient, indoor, and industrial atmospheres. Carbonyls are trapped on our high-purity silica gel adsorbent coated with 2,4-dinitrophenylhydrazine (2,4-DNPH) where they are converted to stable hydrazone derivatives. The derivatives are eluted from the tube in acetonitrile and ...

  • Cryotherapy is Cool

    Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation.  Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack ...

  • A Complete Guide to Benzene

    Why is Benzene so hazardous? VOCs have a significant vapour pressure at normal ambient temperature which means they evaporate (volatilise) at low temperatures so they can easily enter the body through normal breathing but can also be absorbed through the skin or by swallowing material containing it. The effects on worker’s health depends upon how much benzene they are ...
