  • Olfasense - Nalophan gas sampling bags

    Olfasense - Nalophan gas sampling bags

    Our ready-to-use sample bags have been designed to meet the quality requirements of EN 13725, to minimise the risk of contamination of odour samples. Olfasense’s sample bags are made of Nalophan® and PTFE tubing to minimise surface reactions with sulphurs. Within the ISO 17025 accreditation scope, the Nalophan® is tested according to No. 6.3.2 of the European Norm EN 13725 as well as according to No. 4.3.1 of the German guideline VDI 3880 and is...

  • Olfasense - Tedlar and Kynar gas sampling bags

    Olfasense - Tedlar and Kynar gas sampling bags

    Olfasense is reseller of Kynar and Tedlar sampling bags made from PVDF, offering sizes from 0.5 L to 1000 L. Tedlar and Kynar bags are commonly used for indoor air sampling, waste sites, storage tanks, stack sampling, soil gas sampling, gas blending, calibration test standards, and many other gas sampling needs. Tedlar bags are also recommended by many US EPA methods. The bags can be filled using the Olfasense vacuum air sampling box. Olfasense...

  • Olfasense - CSD30 odour sampling device

    Olfasense - CSD30 odour sampling device

    The CSD30 is a sampling device for collecting air (odour) samples in gas sampling bags, with a default odour sampling duration of 30 minutes. Using the lung principle, the sample flows into the gas sampling bag through the sampling tube only, without passing through pumps or other equipment. The materials used for ‘wetted’ parts that are in contact with the sample flow are PTFE and stainless steel, in compliance with EN 13725. The sample flow is...

  • Olfasense - Standard odour sampling device

    Olfasense - Standard odour sampling device

    Our standard odour sampling device consists of a vacuum container that is evacuated by a vacuum pump. The sampling point and the standard sampler are connected by a probe. When the sampling device is evacuated, the gas sampling bag inside sucks in sample air via the probe. The sampling device is constructed to make sure that none of its components come into contact with the sample air during this process. This device can be used for sample...

  • Olfasense - Vacuum Air Sampling Box

    Olfasense - Vacuum Air Sampling Box

    The Olfasense vacuum air sampling box allows for taking air samples into sampling bags without the sample coming into direct contact with the pump. The box can fill up to 10-liter sampling bags, with a flowmeter allowing to adapt the filling rate of the bag. Through a observation window the operator can watch the inflation progress. The connections can be changed out for every sample to prevent cross contamination through multiple sampling. The...

  • Olfasense - Liquid to gas vaporiser (LiGaVa)

    Olfasense - Liquid to gas vaporiser (LiGaVa)

    The LiGaVa system vaporises any kind of liquid into the gas phase. Because time, volume stream, temperature and amount of liquid are all known variables, it is a highly standardised odour sampling system. It is also simple to operate: just inject a set volume of the liquid sample (e.g. a fragrance, aromatic, alcohol or fuel) into the LiGaVa, which will vaporise it. You can achieve the correct vapour pressure for your particular liquid sample by...

  • Olfasense - Scent Sampler

    Olfasense - Scent Sampler

    It’s always been tricky to take standardised samples directly from the skin and other surfaces. This is a particular issue in the field of cosmetic testing, where the data may be needed for anything from quality control to identifying off-odours. Luckily, Olfasense's innovative scent sampler is a breath of fresh air for anyone faced with this problem. It can take samples directly from the skin or other surfaces (such as fragrance strips), enabling...

  • Olfasense - EPD sample pre-dilution device

    Olfasense - EPD sample pre-dilution device

    The EPD is an easy to use pre-dilution system for highly concentrated odour samples. It has been developed to increase the measuring range at high odorant concentrations for olfactometers. And, because it ensures that the odour concentration of the air is not too high, it also prevents self-contamination of the olfactometer. The EPD is designed for use in olfactometry laboratories and gives the operator the opportunity to process odour samples with...

  • Olfasense - GSP on-site sample pre-dilution device

    Olfasense - GSP on-site sample pre-dilution device

    The GSP dilutes the sample directly at the sampling point. Sample pre-dilution can be performed with nitrogen or synthetic air, whereby the pre-dilution ratio is fixed by the manufacturer (standard 1:10 with individual calibration data). The pre-dilution ratio can, however, be set to different exhaust air conditions on request by substituting the 1:10 screen with a sapphire screen accessible from the outside (e.g. dilution 1:5 or 1:20). The sample...

  • Olfasense - Non-ventilated sampling hood

    Olfasense - Non-ventilated sampling hood

    This hood allows defined sampling of flow area sources with very low discharge speeds (e.g. biofilters and ventilated compost piles). The volume of the exhaust air flow is guided through the hood and the chimney, and is consolidated. The sampling hood has a base surface area of 1m2 and a chimney with a diameter of 150mm. It is easy to transport, as the chimney can be detached from the body of the hood by loosening the four knurled nuts. There...

  • Olfasense - Ventilated sampling hood

    Olfasense - Ventilated sampling hood

    The ventilated sampling hood is used primarily for sampling non-ventilated, odour-emitting solid or liquid area sources. When sampling liquids, floats are attached to the sides of the hood. The hood itself is automatically ventilated by two radial fans with a constant volumetric flow. The inlet fan sucks in outside air via an exchangeable orifice and transports the air from the top into a corner of the hood through an active carbon filter. From...
