INSTRUMENTATION Vacuum pump controller. The Laboxact control, mounted directly to a Laboport pump, includes a manually adjustable regulator, safety-vent valve, and digital vacuum gauge. Laboport pumps are available in an assortment of flow capacities, use premium Teflon and Kalrez resins, are maintenance-free, and do not use pump oil or water for operation. The Laboxact provides control of vacuum levels for a variety of routine jobs with ovens, manifold filtration, rotary evaporation, and desiccation. KNF Neuberger Laser ablation. The UP193HE is an excimer-based laser ablation system designed for solid-sampling introduction to ICP, ICPMS, noble gas MS, and stable isotope MS instruments. The system is ideal for solid sampling of opaque and highly transmissive materials, including quartz, diamonds, and gemstones. Geochemical analysis of fluid inclusions, zircons, calcite, apatite, and basalt can also be performed. The UP193HE features high-energy density at the sample—up to 40 J/cm2—and can target defects and inclusions with spots as small as 4 µm in diameter without fracturing the sample surface. New Wave Research

Recent upgrades include dual 16-bit ADC and redesigned mirror-drive board; FTIR benches with 0.5 cm–1 resolution; a choice of DTGS, MCT, or dual detectors; and a generous sample compartment with a wide selection of sample accessories. Midac
High-pressure pump. The 818 advanced IC pump is specially optimized for ion chromatography and includes electronic controls that have been completely reworked for minimum residual pulsation with increased precision and flow stability. The compact pump unit is compatible with many HPLC and IC systems. Up to four pumps can be combined to form a quaternary high-pressure © 2004 AMERICAN CHEMICAL SOCIETY
gradient system. The serial dual-piston pump with two valves guarantees high performance. Metrohm-Peak
Detector. With its flexible modular design, the Coulochem III platform can be used with any HPLC system. This electrochemical detector readily quantifies picogram to femtogram levels of oxidizable or reducible compounds. Pulse, dc, and scan modules are available. The system uses high-resolution embedded microprocessors to ensure the lowest possible electronic noise, which results in the lowest possible detection limits, widest dynamic range, and greatest speed for compatibility with fast chromatography. Esa Water purifier. The portable Easypure II RF/UV water purification system is well suited for critical organic determinant analyses such as HPLC and GC/MS. The incorporated reservoir allows operation without a permanent source of feed water. The pump output is 1 L/min with resistivity of up to 18.2 megohm-cm TOCs below 3 ppb.
date sample vials of 0.8, 2.0, 10.0, or 20.0 mL. The Cobra L/S is suitable for routine as well as research-level sampling requirements. EST Analytical
X-ray spectrometer. The compact and easy to use Venus 200 spectrometer is configured for optimal performance and speed in widely differing industrial applications for qualitative and quantitative analyses. Sample excitation is through an X-ray tube, and data are collected by using up to three separate measuring systems operating simultaneously. PANalytical LC/MS. The 1D NanoLC proteomics system is the first HPLC system to provide nanoscale LC/MS without flow splitting. By incorporating innovative direct pumping technology, the 1D NanoLC system achieves unsurpassed sensitivity, reliability, and stability. Its automated peak-parking feature lowers the flow rate rapidly during a gradient, effectively eliminating previously complex approaches and saving time. Leap

COLUMNS HPLC columns. Shiseido’s Capcell Pak C18 AQ series is designed with varied types and amounts of silicone polymer and functional groups to retain highly polar compounds and enable the use of 100% water as the mobile phase. The peak shape of basic compounds is symmetrical, even under acidic conditions. The columns are available in capillary, cartridge, semi-microcolumn, and standard dimensions and in 5- and 3-µm particle sizes. JM Science Capillary columns. Valcobond capillary columns are individually tested and have high temperature limits and low-bleed characteristics. Improved upper temperature limits enhance column bake-out and reduce sample carryover and cycle times. Automated deactivation, coating, curing, bonding, and cross-linking produce MScertified bleed characteristics. Vici
