38 Environmental Analysis Scientific-grade Spectrometer with Enhanced VIS-NIR Response
The Maya2000 Pro-VIS-NIR from Ocean Optics (Netherlands) is a back-thinned 2D FFT-CCD spectrometer with high sensitivity, 80% peak quantum efficiency and excellent VIS-NIR response. The Maya2000 Pro-VIS-NIR is ideal for low light-level applications such as Raman, as well as for analysis of gases used in semiconductor processing and measurement of biological samples in the life sciences.
The Maya2000 Pro-VIS-NIR has a low-etalon, scientific-grade detector that provides high quantum efficiency from ~400-1100 nm. Other features include triggering functions for providing accurate timing and synchronisation between the spectrometer and other devices.
Three low-jitter trigger modes and normal (free-running spectral acquisition) operating modes are possible. Applications include pulsing a light source when acquiring a spectra and synchronising spectral acquisition to coordinate with samples moving through a process stream or sensors reaching a certain temperature level.
In addition, Maya2000 Pro-VIS-NIR supports RS-232 communications and has a 30-pin connector and 10 user-programmable digital I/Os. Its enhanced onboard programmable high-speed FPGA controller enables triggering and provides other performance advantages.

Configurable Spectrometer
Avantes (Netherlands) has presented their latest spectrometer innovation. Miniature spectrometers are versatile, portable and well embraced by researchers and engineers worldwide. Until now the technology has not really supported customer demands for flexibility and configurability. Avantes introduces a truly configurable miniature spectrometer that allows you to change your slit and connector on the go. In your laboratory, on the road: it only takes a screw driver to continue your measurements with a new set-up.
Avantes new Avabench-RS enables a microspectrometer that is adaptable to your changing needs: whether you need higher throughput or higher resolution. The Avabench-RS optical bench is the enabling technology for this technological advancement and is now available in all Avantes UV/VIS/NIR AvaSpec spectrometers. Based on the Ultra Low Stray light optical bench, this means you
will get up to 5 times better stray light performance and exceptional thermal and mechanical stability. AvaSpec spectrometers include a choice of 13 different standard gratings, 10 different detector options and many more options and accessories.

On-Site TPH in Soil Measurements in Less Than 10-15 Minutes with Portable Infrared Analysers
On-site analysis of total petroleum hydrocarbon (TPH) concentration levels in soil are easily handled using the InfraCal TOG/TPH Analysers manufactured by Wilks Enterprise (USA). The InfraCal TOG/TPH Analysers are portable infrared (IR) analysers that quickly determine TPH levels in less than 10-15 minutes, including the extraction. Concentrations as low as 10 ppm to well over 10,000 - 20,000 ppm can be easily and accurately measured. Models are available for use with various extracting solvents such as S-316, hexane and perchloroethylene.
InfraCal TOG/TPH Analysers are ideal for soil testing at remediation sites such as leaking underground storage tanks and produced water evaporation ponds. Site managers can obtain on-site measurements and eliminate the need to wait for off-site lab results and save costly down time for remediation equipment.
InfraCal TOG/TPH Analysers are portable (weighing under 5 lbs and operable from a 12 volt power supply) and read out directly in parts per million (ppm) or mg/kg. Sampling requires a few simple steps and can be performed by non- technical personnel.
Reader Reply Card No. New Laqua Range of Meters
Manufacturer of bench top meters HORIBA (Japan) is launching the LAQUA range its latest generation of instruments using the expertise from a company that has been manufacturing pH meters for more than 60 years and sold more than ¼ million instruments.
The range marries high performance with stylish design, industry first, touch screen interface. HORIBA has focused the development of the bench top meter to provide durable user-friendly meters for the laboratory professional. Advanced functionalities and a huge array of electrodes provide high precision, reliable measurement with improved response time in a huge variety of applications - from routine measurement to coping with extreme conditions.
LAQUA series consist of single and dual channel meters that can measure the most commonly used parameters in electrochemistry as pH, ORP, Ion, Conductivity, Resistivity, Salinity, TDS and Temperature and up to six parameters simultaneously. LAQUA’s large capacitance touch screen panel can display easy to understand real time graph, digital or analogue values.
The meter can be calibrated in five points, and has automatic standard solution recognition function for NIST/USA buffer as well as a customisable standard setting, it also complies with Pharmacopoeias standard.
Up to 2,000 data sets can be stored on the device’s internal memory. Data can be saved on to an external memory stick or transferred to a computer via RS-232 or USB connections, and HORIBA provides free of charge data acquisition software. Fully GLP/GMP compliant, the LAQUA can be connected to an external printer. To ensure traceability, data is linked to sample name and user ID as well as calibration information. User account can be created and can be protected with a pin code. The Auto diagnostic function and the electronic user guide with colour pictures are useful feature that allow high performance and reliable measurements at any time.
