Environmental Analysis - UK Focus New Single Chip 24 Bit Digital Temperature Sensor Available


Variohm EuroSensor (UK) has added a new range of single chip digital temperature sensors for SMT assembly to its wide range temperature measurement solutions. The TSYS01 series from Measurement Specialities includes a factory calibrated temperature sensing chip and a 24-bit ADC to provide highly accurate and high resolution temperature information when interfaced to a microcontroller via its SPI or I2C interface. The high accuracy temperature sensor has an operating temperature range of -40°C to +125°C, with a precision of +/- 0.1°C over -5°C to +50°C. The QFN16 sized device includes an additional input for a remote temperature sensing detector - with temperature range adjustment on request.


With low current consumption and low self heating, the TSYS01 is aimed at applications in industrial control, HVACR and heating & cooling systems, as well as automotive, medical, business and consumer equipment applications where precision temperature measurement is becoming increasingly integrated into products.


Variohm EuroSensor provides complete pre-sale and post-sale application support for the Measurement Specialities range which includes sensors for temperature, pressure, force, humidity, torque and vibration and more. A detailed 18-page application note PDF document for the TSYS01, including specifications, installation, interfacing and programming code, is available on request.


Variohm EuroSensor also designs, develops and sources a broad range of position, load, force, and other sensor technologies for demanding measurement applications throughout industry, agriculture, construction, autosports, and research.

New DataTrace Pro Process Monitoring Software Available


Cherwell Laboratories (UK), specialists in products for environmental monitoring and process validation, has introduced DataTrace Pro (DT Pro) integrated software for use with DataTrace wireless data-loggers for critical manufacturing and validation applications. DT Pro offers users greater insight and productivity through the simple creation of process reports to enable analysis and understanding of data whilst complying with regulatory requirements.


DT Pro software is equipped with time-saving features, such as shortcuts to minimise key strokes, intuitive screens and batch functions. New reporting capabilities allow for simplified and customised reporting where field calibrations, logger battery changes and data logging events are automatically incorporated into the audit trail. DT Pro also offers improved password protection and administrative security options, such as electronic signatures and data encryption to ensure FDA 21 CFR Part 11 or GxP compliance.


“The DataTrace Pro software is specifically designed to make our customers’ validation and process reporting easier,” said Andrew Barrow, Sales Manager at Cherwell Laboratories. “It offers greater efficiency by enabling easy data collection and analysis with clear presentation.”


Cherwell Laboratories supplies the complete DataTrace range of fully patented, high-precision data logging systems. Since no wiring is required, they can be used to measure temperature, humidity and pressure directly inside a process or a product during manufacturing with minimal production downtime. DataTrace wireless data loggers are rated as “intrinsically safe” and can operate over a wide temperature range. From chilling, freezing and room temperature to pasteurisation, EtO or steam sterilisation and depyrogenation, DataTrace data loggers provide highly accurate data with remarkable ease.

New Multimode Inlet Enables a Single GC-MS System to Support Multiple Analysis Tasks


Shimadzu (UK) has released the OPTIC-4 Multimode Inlet for Gas Chromatograph Mass Spectrometers to address the growing R&D demand for a single GC-MS system that can accommodate multiple analysis tasks. The introduction of the multimode inlet device is targeted at chemical manufacturers, food producers and university research departments.


Equipped with injection modes capable of accommodating a wide range of sample forms, the OPTIC-4 supports split/splitless injection modes. A further five inlet modes can also be accommodated with the single inlet. The additional modes include: large volume injection mode; inlet derivatisation mode; thermal desorption mode; thermal extraction mode; thermal decomposition (pyrolysis) mode and DMI (Difficult Matrix Introduction) mode.


Utilising a direct heating method, the OPTIC-4 is able to achieve a maximum heating speed of 60°C/sec which enables chromatogram peak spread in thermal decomposition analysis to be suppressed to a minimum. Equipping a system with an optional cryotrap will sharpen chromatogram peaks and improve separation and sensitivity. With a maximum heating speed of 60°C/sec, analysis is possible while the spread of sample bands trapped by the cryo unit can be suppressed to a minimum.


Compound adsorption due to cold spots can be minimised because the OPTIC-4 does


not use switching valves or transfer lines, which is ideal for analysing compounds with a high boiling point, as well as adsorptive and degradable compounds.


The OPTIC-4 can also be used as an inlet for large volume injection analysis. The improved sensitivity due to large volume injection enables simple and easy sample concentration.
