To uncover the crucial information for criminal investigations and legal proceedings, forensic analysts rely on sophisticated methodologies that yield objective and scientifically grounded insights. These approaches include DNA analysis, fingerprinting, ballistics, and toxicology. Explore how robust forensic analysis empowers law enforcement agencies and legal professionals to solve crimes and uphold justice.
Model D-6 is a single mode GC detector, optimized for trace level work in the electron capture mode. IT is available in versions for easy installation on most of the GC's in current use, including the Varian 3800, Shimadzu 17, ThermoFinnigan Trace, Mega, and Top, and Hewlett Packard 5890. Available for 110 VAC and 230 VAC.
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…
Now you can reduce run time, faster than micropacked, by replacing your packed columns with ValcoPLOT HayeSep capillary PLOT columns, with phases available only from VICI. 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. The nitrogen purifier is similar, purifying nitrogen to sub-ppm levels of gaseous impurities. The miniature version of each purifier is designed to be installed in a GC’s flow path immediately upstream of the injector.…
Gas purifiers for specific gases designed to go in-line with the carrier or detector gas supply, these gas purifier modules dramatically reduce contaminant PPM levels in helium, hydrogen, nitrogen, or air. They decrease baseline noise and increase GC/MS sensitivity and replace three traps with one gas purifier.This line includes original equipment gas purifiers for the Agilent Mass Spec and LC Mass Spec. Additional specialized…
Syringes used to fill a loop on a sample injection valve have blunt, smooth ends. The end of the needle must contact the bottom of the valve’s fitting detail uniformly and seal on the outside of the tip to deliver sample with any repeatability. All VICI Precision Sampling syringes for valve injections have smooth, burr-free ends that fit the valve fitting details perfectly. The standard HPLC syringe is our basic C-160 with a 2…
