Determination of the amount of volatile organic compounds (VOC) released by solid or liquid samples. Suitable sample matrices, for example, black mass of recycled batteries, polymer samples, and liquid and solid chemicals. The measurement is performed by placing the investigated sample in a chamber, through which nitrogen is flushed. The nitrogen is led through an absorption cartridge, which traps the VOC compounds. Upon completion of the gas collection, the trapped VOCs are analyzed with thermal desorption-gas chromatography (TD-GC). The measurement can either be performed at ambient temperature, or the sampling chamber can be heated up to 120 °C.

Our δ13C stable isotope analysis determines the ratio of 13C to 12C in a given sample material by a continuous flow isotope ratio mass spectrometer (IRMS). Results are expressed in per mille (‰) as the deviation of the isotope ratio from a standard reference material. We have more than 30 IAEA, USGS, and in-house isotopic standards available to accommodate a wide range of expected ratios. The price and turnaround time displayed apply to conventional sample matrices. The analysis is suitable for a wide range of sample materials, including, but not limited to, those listed in the table below. All of our stable isotope analyses are conducted at ISO 17025-accredited facilities. Please contact us using the form below to arrange testing on your samples.

Determination of the amount of hydrogen fluoride (HF) in a gas sample. Testing is performed by pumping the gas through a gas trap, after which the content of the trap is analyzed. The required pump and gas trap will be delivered to the customer before sampling. The customer performs the sampling and returns the equipment, upon which the analysis is performed. The detection limit depends on the volume of the sampled gas. Please see the details below.

EN 15051-2 standard specifies the measurement of dustiness of bulk materials according to the rotating drum method. It is a widely accepted procedure designed to simulate the handling processes that can generate airborne dust. The material dust, generated by the rotation of the drum, is separated into three different fractions. Inhalable, thoracic, and respirable dustiness mass fractions (in mg/kg and in %, if required) are reported. The inhalable fraction of dustiness is the fraction of particles with an aerodynamic diameter smaller than 100 µm., The thoracic fraction of dustiness is the fraction of particles with an aerodynamic diameter smaller than 10 µm., The respirable fraction of dustiness is the fraction of particles with an aerodynamic diameter smaller than 4.25 µm.. Along with the fractions of the airborne particles, the dustiness potential (very low, low, moderate, or high), the density, and the moisture content of the sample are also reported.
