Robust and easy-to-use soil gas sampler. The VOC-Mole is a stainless steel assembly that is inserted into the ground, allowing soil gas to be sampled onto a sorbent tube, for analysis by thermal desorption (TD)–GC–MS.The VOC-Mole is simple to use and easy to transport, and perfect for any analyst wishing to monitor levels of volatile organic compounds in soil.Features: Organic pollutants pass through holes in the hollow t…

Grab-sampler for air sampling. Easy-VOC is a hand-held device that facilitates the rapid ‘grab’ sample collection of small volumes (<500 mL) of air directly onto sorbent tubes without the need for calibrated pumps.Sorbent tubes attach to the end of the Easy-VOC and air/gas is drawn directly onto the tube. Easy-VOC regulates the flow rate independent of the force used to pull the air through.Grab sampling involves collecting v…

The helium leak detector is a portable, highly sensitive instrument designed to detect helium carrier gas leaks in thermal desorption and GC systems. Gas leaks are indicated with both an indicator lamp display and an audible alarm. The long, flexible probe makes it convenient to detect small and hard-to-reach gas leaks. Using the detector for gases other than helium is easily achieved by changing the polarity setting. The det…

Automated gas chromatography sample preparation for the analysis of Polycyclic Aromatic Hydrocarbons (PAHs) in soil

Discover product solutions for complete PFAS analysis workflow, starting with sample collection and preparation, and standardization and chromatographic analysis 

Polynuclear Aromatic Hydorcarbons (PAHs) are among the most frequently monitored environmental contaminants. Waters PAH columns are optimized for the HPLC analysis of PAHs. These columns achieve baseline resolution and excellent peak symmetry for 16 different target analytes in less than 25 minutes, while employing a simple water/acetonitrile binary gradient method. The resolving power of the PAH columns provides superior pe…

AstraGuard uses advanced CCD array, fibre optic coupled spectroscopy to continuously monitor organic levels in the treatment of drinking, process and waste water. The UV absorbance of water at 254nm is a reliable indicator of its aromatic organic carbon content; many studies have proven a correlation with the traditional laboratory tests like TOC, BOD, COD and DOC. The ease of implementing UV254 as a continuous monitoring syst…

The CAI ZRE NDIR analyzer is based on the infrared absorption characteristics of gases. Us ing a single infrared beam to measure gas concentrations, the ZRE produces highly stable and reliable results. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some o…

The California Analytical Models 600P & 600F digital analyzer product line is designed around a state of the art 16 bit microprocessor, with 16 digital inputs, 16 digital outputs, 16 analog inputs and 4 analog outputs. The analyzer can be manually operate…

FTIR Spectroscopy is an analytical technique which measures the infrared intensity versus wavelength (wave number) of light. The FTIR Spectrometer obtains infrared spectra by collecting an interferogram of a sample signal with an interferometer. FTIR Analyzer(s) Highlights: No Liquid Nitrogen Required Compact, Industrial Design w/Fast Repsonse Proven Rugged Interferometer with Gold Mirrors Heated Standard Stainless St…

In Photoacoustic Spectroscopy (PAS) the gas to be measured is irradiated by modulated light of a pre-selected wavelength. The gas molecules absorb some of the light energy and convert it into an acoustic signal which is detected by a microphone. Photoacoustic IR Analyzer(s) Highlights: Low Sensitivity (From ppb to Percent Levels) Yearly Calibration Minimal Maintenance Measures up to Five Gases + H2O Temperature and…
