New to Market tensive international, end-user research. In a departure from traditional efforts in gas industry hardware design, Linde elected to collaborate with more leading-edge product designers in order to deliver the best user experience in terms of functionality and ergonomic design. Importantly, EVOS employs a uniquely designed, quick-action lever in place of the more traditional hand-wheel mechanism for opening and closing of the valve. This innovative open/close functionality ensures easy opening to improve efficiency, fast closing in case of emergency and, as an extra safety feature, the ability to physically see at a distance whether the valve is open or closed. The cylinder valve design also incorporates several additional new features including: a safety ‘interlock’ button to mitigate the risk of the valve being opened accidentally; a uniquely designed guard to improve user safety and prevent damage to the valve; and an optimal grip design for ease of lifting and to ensure the cylinder can be easily and safely moved via crane to heights. The valve is also capable of oper-

ating 300 bar working pressure — significantly more than standard industry valves; and with the EVOS Ci and VIPR models there is also a real-time content gauge to allow users to see the amount of gas left at a glance. Colin Haden, responsible for packaged gases and hard goods development at Linde, said, “The EVOS range is truly a breakthrough in valve design and represents a leap forward in performance, safety, ergonomics, and efficiency. We are delighted to introduce it to our customers.”

DF-745 SGMax from Servomex

Ground-breaking advances in measurement technology and software control make the new DF-745 SGMax from Servomex (servomex.com) the most sensitive and flexible trace moisture analyzer available for specialty gas applications, according to the company. Building on the success of the original DF-745 SG, the SGMax is a sophisticated process analyzer optimized for measuring moisture in a specialty gas stream. Combining advanced Tuneable Diode Laser

Absorption Spectroscopy (TDL) technology with sophisticated Servomex signal processing software, the SGMax delivers exceptionally accurate moisture level readings with a performance enhanced by drift free operation, low maintenance, and no requirement for a pump. The SGMax is engineered to deliver an ultra-low detection limit (LDL) of just five parts per billion (ppb), the lowest trace moisture measurement level available to specialty gas production without the additional set-up costs or ongoing expense of using a pump. Five ppb LDL means the SGMax delivers unprecedented measurement sensitivity at least twice as low as any comparable analyzer, enabling user product to achieve purity levels previously unavailable from a
