    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 carried to the pre-cut column. Backflush is timed so that only the Diacetyl and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The Diacetyl is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

  • Air monitoring equipments for workplace and personal exposure monitoring

    Many occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.

    Gas analysis & monitoring system for medical gases monitoring

    The measurement of occupational exposure to pollutants in the operating room is an essential tool for the detection of chemical, linked not only to the occurrence of infections and various diseases, but also to reduced alertness and performance of staff. To meet the above requirements, ETG proposes the use of ‘INFRARUN, thanks to the high sensitivity and stability and the very wide dynamic range, INFRARUN is the ideal tool to make a continuous sampling in the short and long-term gaseous contaminants in the field hospital, such as volatile anesthetics, aldehydes, fluorani, isofluorani,, VOC’s, etc.

  • Total Sulfur monitoring

    Total Sulfur includes all the gases described within total reduced sulfur, as well as sulfur dioxide as these compounds are oxidised forms of sulfur. Exposure to sulfur dioxides, and other reduced sulfur based compounds can cause many harmful effects in humans including headaches, general discomfort up to death in large doses. Those with impaired heart or lung function and asthmatics are at increased risk. Sulfur dioxide, one of the major pollutants, is absorbed by soils and plants and captured within and below clouds and in certain circumstances can increase the acidity of rain.

    Mercury monitoring for measuring mercury content in hair

    Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated by difference. Tekran has over 18 application notes available for Tekran 2600 users.

  • HCl Monitoring in Air

    Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have shown that TDLAS equipment provides data that is more accurate than conventional gas monitoring equipment. When calibrated for HCl monitoring, TDLAS is able to detect this gas among other gases present in the area and provide continuous updates with regards to the changes in its concentration.

  • Low frequency noise analysis using XL2

    The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data. The new features are particularly useful in the calculation of immission levels which is defined as the cumulative noise energy to which an individual is exposed over time. Exposure to low-frequency noise over extended periods can lead to a range of health problems including cardio vascular disease, insomnia and depression. The sources of low frequency noise can often be attributed to electricity sub stations, chiller plants and incinerators with continuous noise at frequencies below 200 Hz. XL2 Sound Level Meter records all Data Measuring LFN requires a class 1 sound level meter

    Gas monitoring instruments and systems for print factories

    Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

    Measurement solution for medical workplace monitoring

    In taking a responsible stance on the exposure of workers to any potential hazardous gases, there is a need for workplaces using anaesthetic gases, such as hospital operating rooms or research laboratories, to control the level of waste anaesthetic gas in the ambient air. Anaesthesia machines, ventilators, breathing systems and waste gas scavenging systems will all contribute to te background level of he anaesthetic gases that are present in the environment within a facility, whether those machines are in a good state of repair or not. Recovery rooms can become polluted, for example from gas exhaled by the patient, and clean-up from any spills can remain in the background air for long periods.
