Environmental Analysis 27 The First Portable ‘All-in-One’ Microgas Chromatograph
Pollution S.r.l. Italy (
www.pollution.it) is proud to present his revolutionary microGC. The goal was to obtain a real user friendly, portable and versatile instrument. VEGA-GC microgaschromatograph has been designed both for ‘on-field’ activities in complete autonomy and for continuous ‘on-site’ monitoring. The instrument is based on two changeable analytical modules including a µ-injector, a GC-column and a TCD µ-detector which allow to detect a large number of gas substances. The miniaturization enables quick analysis and high sampling frequencies.
The VEGA-GC in portable configuration is able to carry out analysis on site in complete autonomy since it has, Rechargeable and ‘hot-changing’ batteries, Disposable Carrier gas cylinder and Computer with touch-screen control and ‘MC-PLAN’(management software) build-in.
The software ‘MC-PLAN’, hearth of the system, combines a simple and intuitive interface (thanks to the colour LCD touch-screen integrated on the instrument) and extreme flexibility. It allows personalisation of every monitoring aspects, from the measured substances to the surveys at regular intervals, from the alarm thresholds to the communication modality. The connection with several optional accessories expands the capabilities of Vega-GC. A useful working condition is coupling the microGC with ‘VEGA-MPS’ (multipoint sampler) that effectively allows to monitor changes over time in different sampling points.
VEGA-GC system, properly configured, is also used as a "fixed location" for continuous long-term monitoring. VEGA-GC can be controlled remotely via LAN or with GPRS/UMTS modem allowing checks and/or data downloading, making human presence no longer needed on-site. The Vega-GC can send e-mail or text messages to mobile phone to a list of users constantly informed about any limit values overflow or malfunctions.
The VEGA-GC, thanks to the supplied software and GC technology, is therefore capable to separate, identify and quantify in easy way a wide range of analytical dispersed species (BTEX, mercaptans, anesthetic gases, permanent gases, etc.)

ToF Mass Spectrometer Enables Efficient and Easy Data Acquisition
New Semi-Preparative HPLC Pump
Using over forty years experience of HPLC instrumentation, the Adept HPLC range from Cecil Instruments (UK) has been enhanced, with the newly updated semi-preparative pump. The pump expands and streamlines the modularity of this range.
Each pump has a range of 0.01 to 50 ml/minute and may be used isocratically or with others, to create a high pressure gradient. This makes for smooth, easy and reproducible
transitions in scaling up from analytical to semi-preparative work.
The use of semi-preparative pumps, with AutoQuest autosamplers, column heater chillers, WaveQuest UV/Visible ultra-fast scanning detectors, and fraction collectors makes for complete automation in the long-term, fast and reliable collection of fractions.
The semi-preparative pump is especially useful in the preparation of pure extracts of pesticide residues and environmental contaminants. Comprehensive, versatile, intuitive and easy to use PowerStream software provides for 21 CFR part 11 compliance. Systems are easy and fast to install. They are virtually plug and play.

provides analyst's confidence in their analytical data without compromise. Using exclusive and user-friendly ChromaTOF® software featuring True Signal Deconvolution® enables efficient and easy data acquisition whilst delivering the right results.
LECO's TruTOFTM GC-TOFMS is a cost-
competitive, Time of Flight (ToF) Mass Spectrometry (MS) instrument in a benchtop design. When challenges for today's analysts include matrix interferences, co-eluting analytes of interest, complex samples or LTM (Low Thermal Mass) separations, people resources become increasingly precious. Taking advantage of the mass spectral continuity obtained from TruTOF and combining it with LECO's integrated ChromaTOF software can optimise analytical throughput, increasing laboratory efficiencies.
Analytical efficiency is achieved by the
benefit of TruTOF's data acquisition rates of 80 spectra/second across the full mass range (5 to 1000 u) and data deconvolution. Reliable mass spectral deconvolution & peak ass - ignment relies on the spectral continuity across the chromatographic peak and is the reason ToF-MS is the detector of choice.
LECO's ChromaTOF software package is
world regarded for its flexibility, ease of use and beneficial features including True Signal Deconvolution (TSD). Using one software platform for a fully automated data acquisition and data processing solution also provides the operator with continuity and an organised workspace.
TruTOF has both electron impact (EI) and chemical ionisation (CI) 'plug-and-play' ion source options for optimal flexibility in the laboratory. Choosing LECO's TruTOF GC- TOFMS reduces the analytical load and enables the real challenges in today's world to be addressed.

Reader Reply Card no 96 Total Oil and Grease in Water – On-site CFC-Free!
Eralytics (Austria), proudly presents the Eracheck - the ultimate solution for the fast and easy measurement of sub-ppm concentrations of total petroleum hydrocarbons in water and soil. The innovative and patented QCL-IR (Quantum Cascade Laser Infra-Red) measuring technology finally allows the CFC-free testing of TPH in water samples.
A quick and easy field analysis method for determining oil and grease concentration levels is important for offshore oil platforms, refineries and oil depots. With the manufacture of Freon 113 banned by the Montreal Protocol, older ASTM methods like ASTM D 3921 that used infrared analysis and Freon as the extraction solvent had to be replaced.
The Eracheck uses a very similar extraction procedure, but also comes with the CFC-free, cheap and easily available solvents Cyclohexane or Cyclopentan. It offers maximum precision in sub-ppm range over a wide measuring range (0.5 to 1000 ppm) in excellent correlation to ASTM D 3921 and D 7066. Eracheck is a portable stand-alone analyser equipped with the latest communication technology. Data can be saved onto a memory stick and documented in popular PC worksheet formats for further data analysis.
