SERVOPRO DF high purity

The DF-730 monitors ultra-trace moisture in HCl

The DF-730 is an ultra-trace moisture analyzer monitors the electronics-grade, high-purity hydrogen chloride (HCl) gas used in semiconductor fabs.

Trace moisture measurements for electronic grade HCI gas production

Designed to analyze moisture contamination in electronics grade HCl used in semiconductor fabs, the DF-730 is ideal for quality control and leak detection applications.

Servomex’s industry-leading Tunable Diode Laser (TDL) sensing technology and a robust Herriot Cell enables a broad measurement range of 10 part-per-billion (ppb) to 10 parts-per-million (ppm).

By ensuring moisture only comes into contact with minimal optical components, the DF-730’s performance is unaffected by loss in mirror reflectivity – ensuring a fast response measurement that is stable, accurate and consistent.

Optimized to deliver affordability over the life of the analyzer

The DF-730’s leading-edge TDL sensing technology provides zero drift, helping to extend maintenance periods and reduce calibration needs.

With its high performance, ultra-stable monitoring capability and considerable operational cost-savings, the DF-730 is an ideal purity monitoring solution for semiconductor fabs.

High stability coulometric trace and percent measurements

When you require quality control of electronics grade HCI gas, you need a moisture analyzer that delivers consistent, reliable measurements with sensitive performance. A flexible monitoring range is a must, as is a sensing technology that operates effectively for extended periods – even with significant signal loss. No matter what your application needs, you’ll want a moisture analyzer that can reduce your ongoing costs and provide operational efficiencies. At Servomex, we don’t believe you should have to compromise.

A no compromise solution

The DF-730 is specifically designed to meet your application needs, addressing the high quality and performance criteria demanded by semiconductor manufacturers. This device uses high stability TDL sensing and a robust Herriot Cell, helping to minimize water contact with optical components. This eliminates loss of mirror reflectivity issues and allows the DF-730 to deliver reliable baseline measurements. A broad measurement range of 1ppb-10ppm ensures flexible performance in the majority of process conditions. This advanced performance makes the DF-730 the ideal monitoring solution for your application needs.

Simple maintenance and reduced ongoing costs

Added to its considerable monitoring capability is the DF-730’s ability to reduce ongoing costs. The use of patented leading-edge TDL sensing technology means there is zero drift, reduced calibration needs and minimal ongoing maintenance. Engineered into a resilient, high performance design, the DF-730 offers users an extensive operational life with low cost-of-ownership.
