    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...

    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.

    Measurement of diacetyl in ambient air to monitor workplace exposure limits.

    The Series 8900 Diacetyl Analyzer provides direct measurement of Diacetyl in ambient air. This instrument is utilized for environmental monitoring and to monitor workplace exposure limits. The Series 8900 Analyzer for Diacetyl employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is...

    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

  • Integrated real-time gas analysis solution for semi-gases industry

    CIC Photonics first applied its IRGAS technology to semi-gases when a major semiconductor equipment manufacturer, Applied Materials, requested a demo of its capability to monitor gas quality for epitaxial reactor applications; that was in year 2000. The IRGAS System met all of the technical requirements, which included ppb sensitivity for moisture as an impurity, gas cell chemical resistance to both acid and basic semi-gases, and fast concentration tracking time response.

  • Smoke generator devices for lev testing, spray booth clearance testing & air testing

    For many years, materials containing isocyanate have been the single biggest cause of occupational asthma in the UK. Vehicle paint sprayers are 80 times more likely to develop occupational asthma than workers in other industries. This is caused by the inhalation of the fine paint mist that is generated when paint spraying. There is a requirement for the measurement and display of `clearance times` for spray booths / rooms set by the HSE and the Motor Vehicle Repair (MVR) to meet the requirements of Control of...
