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…

Hollow, flow-through plunger with integrated 3-way valve designed for liquid and gases, with a push button on/off valve at the front end. The new Precision Sampling hollow plunger syringe with two integrated valves opens a whole new world of application possibilities: Dispense a viscous sample more easily by introducing it into the rear of the syringe instead of drawing it up through the needle. Eliminate sample-to-sample cros…

The Dual Layer PEEK tubing eliminates any concern that a critical sample stream could be contaminated by pigments used to color code the tubing.  The pigmented layer surrounds a separate but integrally-bonded inner layer of natural PEEK. The 1/16" OD tubing is available in standard sizes, or in OEM quantities with any ID you specify, from .002" to .030". The ID tolerance of ±.001" is equivalent to or better than that of tubing…

The Advantages at a Glance Ready to use columns No more laborious cleaning of Glass Columns Easy handling Reduced Costs- the more samples the more cost effective Certified Columns Excellent Performance The determination of the hydrocarbon oil index in surface, industrial and process water in compliance with EN ISO 9377-2 (H53) is daily routine in many laboratories. Using intelligent sample preparation, time and costs for the a…

"Extend-C18 columns incorporate a unique patented bidentate silane, combined with a double-endcapping process that protects the silica from dissolution at high pH - up to pH 11.5. Columns are best applied for separations of compounds that are either (1) basic and have little or no retention at low or intermediate pHs, (2) more stable or more soluble at high pH, or (3) basic and show poor peak shape at low or intermediate pH.…

Thermal desorption (TD) combines sample preparation, extraction, and injection into a single automated process for the analysis of volatile and semi-volatile organic compounds (VOC and SVOC).
