  • 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 ...

  • Mold! mold! its everywhere! ...so what!

      Ubiquitous is my big word for the week.  Webster"s definition is “existing or being everywhere at the same time:  constantly encountered.” This describes the situation with molds.  They don"t magically appear or re-incarnate when conditions are right.  They ...

  • Modern Technology Closes the Gap caused by the Deficiencies in Traditional Analog Air Sampling Instrument Technology

    Smart air sampling instruments can reduce, minimize and often eliminate the deficiencies of traditional analog air sampling instruments at a time when the industry needs maximum credibility on health and safety issues in preparation for the resurgence of commercial nuclear power plant construction on a worldwide basis. The rapid evolution of microprocessor technology since the mid 1980s has ...

  • Mold! Mold! It’s Everywhere! So What?

    Yes, Mold Is Everywhere! Mold is certainly a problem in many buildings, homes, apartments, condos, offices, factories, warehouses, public buildings. Yes, mold is everywhere. In case you didn’t know, it’s outdoors, as well as indoors. Essentially all molds indoors come from outdoors. The problem occurs when the outdoors mold levels—usually at a level most people can ...

  • Decontaminating Groundwater Sampling Devices

    These studies are the second part of a two year project that examines decontaminating groundwater sampling devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent wash and rinse followed by hot air drying (105°C) was the most ...
