Environmental Analysis 35 Our Genius Range has Evolved
Higher output and a small footprint make Genius2 gas generators the perfect prodigy As your laboratory needs continually evolve so too does Peak Scientific’s (UK) Genius range of Gas Generators.
With our customary touch of innovation we have developed the sleek new Genius2 models and now lead the pack with exceptional performance and real value for money.
The transformation is remarkable. The new 3010, 3020, and 3030 Genius2 generators have the unique benefit of double the gas flow, supporting multiple instruments with individual control, all built into the one, space-saving casing.
• The Genius² 3010 has been designed specifically as a stand-alone system to provide gas to single LCMS applications which require a high nitrogen flow.
• The Genius² 3020 combines’ two individual systems with separate Nitrogen outputs into a single compact unit, thus allowing two separate Mass Spectrometers to be supplied by the same Generator with independent control.
• The Genius² 3030 combines 2 individual systems with separate Curtain, Source & Exhaust gasses for AB SCIEX LCMS instruments supplied by the same Generator with independent control, and is compatible with the full AB SCIEX range.

New Application for Fast and Selective Detection of Chelating Agents in Drinking Water
Dionex (USA) is pleased to announce the release of Application Note 268: Determination of Chelating Agents in Drinking Water and Wastewater Samples. Chelating agents have multiple industrial applications and therefore can sometimes be found in wastewater and drinking water. Some studies suggest that these chelating agents can have biological impact at concentrations greater than 1 mg/L. Based on this, some regulatory bodies have specified concentration limits for chelators in drinking water. This Application Note describes how to separate four common chelators easily using a Dionex IonPac®
AS7 column. Using pulsed amperometric
detection with a disposable platinum working electrode, chelating agents were detected below the required sensitivity. This method features direct and selective detection and was successfully applied to drinking and wastewater samples.

Multi-Hop Data Radio Allows Wireless Connection of Modbus Nodes in Up to 50 Locations
The new Multi-Hop Data Radio from Banner Engineering (Belgium) extends the reach of the company’s SureCross wireless systems by repeating transmissions in 3 km ‘hops’ to a multi-hop total of 20 km or more.
Multiple units can be placed to allow signals to pass over hills and other obstacles that would block a single wireless hop.
The Multi-Hop Data Radio can be used to connect a wide variety of field devices directly, including PLC’s, Controllers, HMI’s, DCS’s, transmitters, level, pressure and temperature sensors.
It allows extension of the widely used Modbus communication protocol to many applications where wiring is impractical because of distance or accessibility. It can also be connected with digital, analog or temperature signals using other Banner wireless products.
Applications for the multi-hop data radio include; irrigation , water & wastewater treatment, facilities monitoring and chemical processing.
The large wireless networks enabled by the new radio provide previously unavailable information to users in a wide range of industries.
In Irrigation, soil moisture can be measured, zone valves can be operated and flow rate measured. More traditional applications include tank level, pressure, flow and temperature monitoring in a variety of markets.
Using the Multi-Hop Data Radio, clusters can be combined and connected to create systems with 2,400 wireless points, covering over 100 square kilometers. For even larger systems, multiple wireless networks can co-exist in the same physical area without interference.
The radios are configured for rapid, easy connection to all remote and central control elements in a network. They can be powered by 10-30 VDC, battery or solar power supply, allowing wireless repeaters to be placed where no power is available.

Online Humidity Calculator Also Calculates Measurement Uncertainty
The free humidity calculator from E+E Elektronik (Austria) is used for the rapid conversion of humidity measurements.
You can fast and quickly calculate from temperature and relative humidity the dew point, frost point, mixing ration or other humidity measurements with ease.
Uniquely, the humidity calculator also includes measurement uncertainties in the calculation.
This is helpful for obtaining realistic and reliable overall uncertainties based on the specification of the measuring device.
The humidity calculator can be used online. This does not require any program to be installed on your PC.
