    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.

    Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. We investigated the performance of the LC-MS and LC-MS-MS methods in the analysis of isocyanates using the new ASSET™ EZ4-NCO Dry Sampler. We found that the analytical method can successfully reach the quantitation limit for most isocyanates of 5 ng/mL in the final sample when LC-MS-MS analysis was used and the quantitation limit of 10 ng/mL when LC-MS analysis was used. All 11 compounds were well-resolved chromatographically using a 15 cm Ascentis Express C18 column.

    Baseline® 9100 Residual Solvent Analysis — Ethanol, Isopropanol, and Acetone

    MOCON’s Baseline® Series 9100 Gas Chromatograph equipped with a photoionization detector (PID) provides a quick, cost effective quantitative analysis of IPA and acetone in air at levels in the ppb and sub-ppb range with no preconcentration necessary. Isopropanol and acetone are detected and accurately quantified to sub-ppb levels in under 3 minutes with ethanol producing no interference. The instrument is sensitive to below 5 ppb for both IPA and acetone employing the MOCON Baseline® standard PID or 0.1 ppb using the MOCON Baseline® high sensitivity PID.

    Monitoring of mercury in ambient air

    Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitativ e determination of mercury in vari ous environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/RA-915+/RA- 915Light with Zeeman background correction provides di rect real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of me rcury concentration in ambient air.

    Direct AA Mercury determination in cosmetics

    INTRODUCTION

    High mercury concentration can be found in such cosmetic products as skin lightening soaps and creams, makeup cleansing products, and mascara.

    Mercury in cosmetics exists as inorganic and organic compounds. Inorganic mercury (e.g. ammoniated mercury) is used in skin lightening soaps and creams. Organic mercury compounds, such as thiomersal, are used as cosmetic preservatives in makeup cleansing products and mascara.

    Analytical instruments for elemental analysis

    Elemental analysis is a generic term for a group of applications which deal with the analysis of a variety of materials (chemicals, liquids, polymers, waste material, etc.) for their elemental or isotopic properties. Typical examples of elemental analysis techniques where mass flow control plays a key role are Total Organic Carbon (TOC) or Total Organic Halides (TOX).

    Air monitoring for laboratories

    Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.

    Common air monitoring applications include:

    • Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
    • Asbestos sampling and analysis

  • Smoke generator device for building envelope, energy studies & air tightness testing

    The air tightness or leakage rate of a building is the uncontrolled flow of air through holes, gaps and cracks in the fabric of a building, which may not be detectable simply by looking at the outside of the building. Filling a building or void with smoke and pressurising that volume, will result in a visible discharge of smoke from any problem areas. Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with smoke and ideally adding a small amount of pressure to the area being tested, will result in a visible discharge of smoke and, simply put, the greater the volume of smoke, the bigger the leak.
