New High Performance Platform and Chromatography Data System
Tomeet the demand for clean, dry instrument- quality compressed air for Chromatography in the laboratory, JUN-AIR produces a range of oil-less air compressors that offer an unrivalled combination of low noise levels, reliability, long life and low maintenance.
The compressors are suitable for most types including GC-FID, GC-
FPD, GC-NPD, GC-ECD, GC-TCD, GC-ATD, GC-AED, GC-ELCD and Hall. Chromatography uses only a small amount of gas – usually zero air or zero nitrogen. In order to supply the base level air used
Improving water quality with Trace Enrichment technology
Anatune (UK) has completed the installation and commissioning of two Trace Enrichment HPLC systems in the Netherlands.
One of the systems, which were supplied to Rijkswaterstaat, is
installed on a bargemoored on the riverMaas close to the Belgian border, where it operates completely unattended taking 100ml water samples fromthe river every hour, extracting the target compounds and thenmeasuring themusing HPLC. Results are automatically communicated to Aqualarm– a systemused tomonitor the water quality of rivers using datameasurement. Should pre-set concentration thresholds be exceeded alarms are triggered automatically.
Rijkswaterstaat’sGerard Stroomberg commented: “Anatune’s Trace Enrichment unit, the TE100, replaces a systemthat had been operational since 1992. The replacement was implemented with theminimumdown time and we are very pleased with the performance of both the instrument itself and Anatune’s team. The systemhas already given us our first alarmfor two unknown compounds that we frequently see in the river. Being able to constantlymonitor these uncalibrated compounds on the new systemis proof of the pudding for us!”
BobGreen, Anatune’s TechnicalDirector, said: “I anticipate significant demand for Trace Enrichment HPLC over the next few years. Worldwide, we see an important role for the TE 100 in the protection of drinking water supplies frompollution spikes in water sources.”
Anatune is also helping waste procedures to control discharges within safe agreed limits through Trace Enrichment technology, which offers increased sensitivity and robustness over conventional HPLC techniques. Formore information visit

as a flame gas or carrier gas for zero air applications the compressor needs to be fitted with a dryer/scrubber to remove hydrocarbons/CO2
.
Most Chromatography applications use oil-less compressors and with decibel ratings as low as 47 dB(A) when housed in an attractive soundproof cabinet, JUN-AIR’s oil-less range has the lowest noise levels available, making them ideal for installation within laboratory environments and even in or near individual workstations.
To ensure the highest air quality throughout the lifetime of the oil-less compressor range, receivers are internally powder-coated to avoid corrosion. Adsorption dryers remove moisture to ensure 100% dry, clean oil free compressed air, with pressure dewpoints of -40 and -70 deg C. The dryer is located upstream of the receiver so the receiver only stores dry air. Units feature a unique cooling system and wear- resisting piston rings, and are designed for 100% continuous operation up to 10 bar maximum pressure. Higher pressure units are available.

New LC Offers Best-in-Class Specifications in All HPLC, UHPLC and LC/MS Categories
Agilent Technologies Inc. introduce the Agilent 1290 Infinity Liquid Chromatography System, designed to deliver significantly greater power, speed and sensitivity for enhanced performance in the high-end Ultra High Performance Liquid Chromatography (UHPLC) market.
"The debate about UHPLC is over," said Patrick Kaltenbach, Agilent general
manager, Liquid Chromatography Business. "We were very ambitious in setting the design criteria for this completely new system, to meet present day demands and also to serve future needs for higher throughput, sensitivity and resolution.When I listen to what our beta site customers tell us, I am very confident that we've succeeded."
"The Agilent 1290 Infinity LC enables separations in seconds, faster than any instrument before," said Daniel Zimmerli, senior technology coordinator at Hoffmann-La Roche in Basel, Switzerland.
"Limits of detection for the pharmaceutical impurities were as low as 0.001% relative to the main compound using the new diode array detector," said Dr. Pat Sandra of the Research Institute for Chromatography in Belgium, another early access user. "This is more than one order of magnitude lower than required by U.S. FDA." For more information visit
