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
Standard x-ray sources for lab based instruments are Al Kα or Mg Kα which provide photons with 1486.6eV and 1254.6eV energy respectively. Here we demonstrate the use of a monochromatic, Ag Lα x-ray source which uses the second order diffraction of the same quartz crystals as used for Al Kα, allowing it to be easily accommodated on a modern spectrometer. The photon energy of Ag Lα is 2984.2 eV, approximately twice that of Al Kα (1486.6 eV). This greater energy leads not only to...
Permeation tubes emits the compound with a constant rate and constant temperature, permeation rate have a exponential dependence from the temperature: it increases around 7% for a increase of 1°C. To generate gas standard with accuracy is necessary a thermostation with accuracy ±0,1°C. The tube (or more tubes) are placed into “U” glass older and immersed in thermostatic bath, the diluent air or nitrogen is pre-heated on bed of glass spheres.

Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.
Are you continuously seeking to improve your safety, health and environmental standards, while striving for increased productivity and product quality? With METTLER TOLEDO’s solutions for hazardous areas, apparent contrasts turn into one set of standards. Our wide selection of intrinsically safe weighing systems includes balances, indicators and accessories, weighing modules, and weighing platforms of several sizes, shapes and capacities.
Forensic labs are improving throughput and eliminating backlog by using DART. Presentation of sample and standards is routine and requires just seconds per sample to determine quantity and quality of seized narcotics and OTC drugs of abuse. Synthetic cannabinoids and bath salts are easily detected and identified with confirmation using simple mass spectrometry methods and comparison with NIST library standards. Explosives, arson, counterfeit currency, tax stamps and even drugs in body fluids present no problem...
The highest standards of accuracy and reliability are required in laboratories and medical devices. STS products are perfectly suited to this purpose – an example is their use in pressure and measurements of dialysis equipment.
NMR reaction monitoring is an excellent technique for determining reaction kinetics as well as reaction end points. The measurements are quantitative with only minimal calibration. The signal has a linear response to concentration and it is generally not sensitive to the matrix. The measurement is of the complete sample and is non-destructive. The Spinsolve high-resolution benchtop NMR spectrometer can be installed directly in the fume hood of a chemistry lab to monitor the progress of chemical reactions...
The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.
Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.
This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.
Although applications in this area advance, there is still a clear demand to get new portable and...
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives...
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
This application package is a `ready to go` calibration kit for xrf instruments. Fusion technology is ideal for analysing oxidic materials like ashes. It performs with the highest precision possible in xrf sample preparation. Primarily power stations and their control laboratories have to check the ash from the burning process of black and brown coal. Two standard DIN and ASTM methods describe the testing in detail. FLUXANA is able to deliver both methods ready from the bench.
A lot of research is carried out in laboratory and on real fires as to the gaseous substances produced in fire effluent. Measurement principles using analytical instrumentation are becoming more widely used in fire testing, due to the quick, real-time nature of the measurements. ISO 19702 is an international standard developed for the use of FTIR analysers in the analysis of gas from fire effluents. Further to this, local test standards such as DIN 5510, applicable to the railway industry, can provide further...
