    Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

    Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA –...

    Gas monitoring instruments and systems for stack testing according to EPA test method 320

    The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B...

    Ambient air quality monitoring solutions for benzene fence-line monitoring

    To monitor benzene emissions can be a challenge, but OPSIS makes it easy. Benzene is an aromatic hydrocarbon liquid that evaporates quickly if exposed to ambient air. It is one of the most commonly used substances in the chemical industry and it is known to cause cancer. For this reason, refineries in the United States must start monitoring fugitive emissions of benzene from January 30, 2018. This is part of the 2015 U.S. EPA Petroleum Refinery rule. In case a yearly rolling average of benzene concentrations...

  • RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

    A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages. The...

  • Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas

    Introduction Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2...

  • Measurement solution for formaldehyde FTIR measurement

    Reciprocating internal combustion engines burning natural gas are a source of formaldehyde emissions. There are strict tolerances imposed on operators of engines to ensure that formaldehyde is removed effectively and that formaldehyde emissions are below published limits. The only instrumental method for formaldehyde monitoring is FTIR, following procedures such as US EPA Method 320 and Environment Agency TGN M22. Protea’s FTIR gas analysers have been specifically designed to follow these methods and our...

  • Particulate monitoring for continuous emissions

    With the advent of specific process emission limits being defined, continuous particulate monitoring has become a regulatory requirement for many industries. smoke stack #1Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere. There is no known method of continuously measuring particulate concentration by direct measurement and therefore, all continuous particulate measurement methods are inferential. Each method involves the measurement...
