Environmental monitoring and testing assess the quality of our air, water, soil, and overall ecosystems. Using advanced technologies and analytical methods, environmental scientists collect and analyze samples to measure levels of pollutants, contaminants, and other factors impacting environmental health. By monitoring changes over time and identifying potential risks to human health, this field plays a vital role in informing policy decisions and implementing effective mitigation strategies. Explore how environmental monitoring and testing contribute to safeguarding our planet's well-being and promoting sustainable development.
Replacement gaskets are available with the vacuum manifold assembly. The gasket can become worn over time and the seal between the plate and the manifold will be affected. This may result in poor vacuum pressure and negatively effect flow rates. The gasket should be checked regularly and replaced when it becomes worn.
EmporeTM Tape Pads are intended for sealing unused portions of a 96-well solid phase extraction plate during vacuum processing to enable vacuum to be uniformly applied to each well being used. Use a clean sheet each time for maximum sealing ability. Note: these tape sheets are not intended for sealing collection plates prior to sample injection because the adhesive may clog the injection needle.
Empore Filter Aid 400 has been shown to improve flow rates and recoveries for separation and filtration of water samples containing suspended solids. When placed on top of the Empore™ Extraction Disk at a depth of about 1 cm, Empore™ Filter Aid 400 acts as depth filter to inhibit the migration of suspended solids to the surface of the disk. This reduces extraction time and improves rates and recovery of analytes.

Reduced breakdown liners Our improved injection port liner reduces breakdown of endrin and DDT during injections while increasing the interval between liner changes. The problem DDT and Endrin are easily degraded in the injection port; with non-deactivated liners and those filled with non-deactivated glass wool, Endrin breakdown can be as high as 98%. EPA method 8081A states "If degradation of either DDT or Endrin exceeds 15%,…
VICI AG uses proprietary liquid phase processing to produce low bleed characteristics while maintaining identical retention characteristics to the phases you are used to. These processes combined with proprietary coating, curing, bonding, and crosslinking produce MS-certified bleed characteristics equal to the best. Improved upper temperature limits enhance column "bake out", reducing sample carryover and cycle times. ValcoBon…

Our proprietary phase processing produces the first capillary PLOT columns with characteristics identical to HayeSep packed columns. The ValcoPLOT line also includes Molesieve and Alumina PLOT columns. Visit VICI AG website to veiw now.
Permeation tubes are small, inert capsules containing a pure chemical compound in a two phase equilibrium between its gas phase and its liquid or solid phase. They are used to generate a stable concentration of a specific trace chemical. At a constant temperature, the device emits the compound through its permeable portion at a constant rate. They are typically inserted into a carrier flow to generate test atmospheres for c…

Patented G-Cal permeation tubes offer a proven and repeatable means of generating a desired gas or vapor concentrations. The permeant gas escapes through the proprietary membrane system and mixes with a carrier gas (nitrogen is the most common) at a controlled flow rate to obtain a known mixture in ppm or ppb. Applications include calibration of gas monitoring systems and chromatographs, accuracy check of gas detectors, and ge…
Ultra-high capacity for the contaminant of interest; either Moisture, Hydrocarbons, Oxygen, Sulfur and Mercury. For applications with a single contaminant of interest, high capacity contaminant specific traps are your best option, since they generally have four times as much capacity for the specific contaminant as a purifier. This translates to a capacity that exceeds twelve standard type "A" tanks of gas or the equivalent of…
VICI AG heated helium purifier provides point-of-use purification of helium or other noble gases, such as Ar, Ne, Kr, and Xe, to sub-ppm levels of reactive gaseous impurities, removing even nitrogen and methane.
