• Pretreatment design: To support stable gas analysis under coal-gasification conditions, Gasboard-9021 incorporates a pretreatment design adapted to high-temperature syngas containing tar vapors, moisture and particulates. Straight-tube or steam-heated sampling probes can be selected according to tar loading to prevent condensation and blockage within the ...
As autumn arrives, shorter days and cooler weather bring not only colorful foliage but also shifts in water quality and environmental conditions. Seasonal changes can affect runoff, groundwater, and surface water supplies, making environmental sampling and water filtration more important than ever. Behind the scenes, advanced materials like fluoropolymers play a key role in ensuring accurate, ...
Suited for laboratories of all sizes, the instrument revolutionises osmolality testing with innovative flowthrough technology that eliminates the need for consumables by pipetting samples directly from primary tubes, while performing testing and cleaning within the device. ...
The ActiveCount Remote Impactor Kit is designed to provide a flexible, modular solution for viable sampling in critical environments. Whether you rely on a house vacuum system, use an ActiveCount viable sampler, or require a remote sampling setup, this kit is engineered to adapt seamlessly to your existing processes and scale as your needs evolve. ...
As winter melts into spring, environmental field teams gear up for one of the busiest times of the year: the spring sampling season. With snowmelt runoff, rising groundwater levels, and increased mobility in field conditions, spring is a critical window for collecting representative groundwater samples—especially in regions impacted by agricultural runoff or legacy contamination. A recent ...
In the quest for cleaner water and more accurate environmental monitoring, advancements in water sampling methods are essential. Among the latest breakthroughs, PTFE (polytetrafluoroethylene) tubing is proving to be a game-changer, setting new standards for efficiency, reliability, and precision in water ...
In 2024 our knowledge center webinar series provided a comprehensive exploration into the latest advancements and best practices in cleanroom monitoring and environmental control. Covering a wide array of topics, from fundamental techniques to cutting-edge technologies, these sessions aimed to equip professionals with the knowledge and tools necessary to maintain compliance and ensure optimal ...
It reviews the misinterpretation of clause C.4.1.2 in Annex C of ISO 14644-1, which suggests the use of 1 m tubing length for sampling macroparticles. The purpose of clause C.4.1.2 is to also describe the importance of additional functions of interpreting and understanding, For classification where accuracy is required, the quality of the ...
Transfer the sample to a new 1.5ml centrifuge tube.|Clean the sample with a cleansing solution.|Centrifuge the sample for 5 minutes at 10000rpm using a centrifuge.|Discard the supernatant.|Add the reagent and mix well.|Incubate the sample in a 56°C water bath for 10 minutes.|Centrifuge the sample ...
Capillary ElectrophoresisCapillary electrophoresis - Protein samples are applied to small glass tubes and move under the action of an electric field. ...
Analysis of VOCs in air generally includes sample pretreatment and qualitative and quantitative detection. Pretreatment Methods Due to the complex composition in the air, air samples need to be pretreated before the detection of volatile organic compounds in the air. At present, common sample pretreatment methods include solid adsorption/carbon ...
There were several software packages available on the market, but none which provided a complete solution to manage samples, the sample source (in Dr Lindsay’s case – the patient) and the storage area. ...
Highlights: ●Adaptable from 1 to 3 lasers, from 4 to 14 fluorescent colors; ●Autoloader with multiple loading options: 96-well standard, 40-well tube racks and 40 EP tube racks; ●2 sampling modes: 1) quantitive sampling (absolute count by volumetric method), 2) continuous sample injection; ●Patented ...
It must be high enough to volatilize the target compounds but low enough to prevent thermal degradation of the sample. Heating Rate: The rate at which the sample is heated affects desorption kinetics. Higher heating rates may lead to faster desorption but can also increase the risk of sample degradation. Sample Matrix: The nature ...
NDIR sensors operate on the principle of molecules absorbing specific wavelengths of infrared light. Air samples are collected in a tube and subsequently analyzed under a source of light. ...

The most common method of leak detection currently employed are “Passive Sampling Tubes” (PST), which are small tubes with carbon sorbent material inside to trap benzene. PSTs are hung around the perimeter (aka fenceline) of the facility and uncapped to expose them to air. After two weeks of sample collection, the ...
Aerosol Devices’ Braden Stump recently recorded a webinar to be able to provide a reference to people looking to learn more about condensation growth tube technology and Aerosol Devices’ line of products. You can watch the video at the link ...
Every month we will highlight our pick for Map of the Month to show how our spectrometers can be used to reveal all the hidden secrets in your samples.AugustSingle-wall carbon nanotubes (SWCNTs) have unique electrical, thermal, mechanical, and optical properties which make them attractive for a wide variety of applications; ranging from drug delivery to battery electrodes.SWCNTs are interesting ...
After a patient coughs into the tube, the technician closes the plunger and rotates the upper half of the tube, thereby engaging the tube’s dynamics to create a disc of cough sample and position it over the biosensor. Closing the tube effectively seals the Breathalyzer and protects the technician from ...
How it works The TB Breathalyser comprises a single-use disposable sample collection tube and a multi-use reader. The patient coughs into the collection tube, at the bottom of which is a glass bio-sensor coated with a patented bio-chemical coating formulated to react with the TB bacilli. A simple push-and-twist action automatically seals the ...
