SERVOPRO DF high purity

The DF-750 is the leading choice in moisture analysis for the semiconductor industry

The DF-750 is a trace/ultra-trace moisture analyzer optimized for measurements in the ultra-high-purity (UHP) gases used in 300mm semiconductor fabs.

Moisture measurements for quality control in semiconductor fabs

Designed specifically to make trace and ultra-trace moisture measurements in a range of UHP gases, the DF-750 is optimized for 300mm semiconductor fabs. It measures moisture as a contaminant in the electronics grade gases nitrogen, hydrogen, helium, argon and oxygen.

Tunable Diode Laser (TDL) sensing technology delivers an industry-leading 100 parts-per-trillion (ppt) Lower Detection Limit (LDL), ensuring the DF-750’s stable, highly accurate measurements meet the precise monitoring needs of semiconductor production.

The robust DF-750 has low lifetime maintenance requirements and delivers zero-drift stability, greatly extending calibration intervals. This low cost- of-ownership combined with exceptional measurement performance means that the DF-750 is the first-choice analytical solution for UHP gas quality checks.

High stability TDL trace/ultra-trace measurements

Ultra-trace qualification of UHP electronic gases is essential for semiconductor fabrication. You need a moisture analyzer
that can deliver high stability measurements with sensitive and consistent performance. An accurate and low LDL is a must, as is the need to easily store and recall data/calibration records. No matter what your requirements, you’ll want a moisture analyzer that can provide operational efficiencies. We don’t believe you should
have to compromise.

A no compromise solution

The DF-750 is designed to meet the exceptional gas purity standards demanded by semiconductor manufacturers worldwide. Utilizing leading-edge TDL sensing technology, housed in a robust and resilient Herriot Cell, the DF-750 avoids moisture contact with optical sensing components. The result is an analyzer that delivers an ultra-sensitive, industry-leading 100ppt Lower Detection Limit, ideal for checking for minute levels of moisture in a wide range of UHP electronics grade
gases, including N2, H2, He, Ar and O2. With data recorded and readily available through flexible storage and recall functions, the DF-750 is the complete solution for UHP gas monitoring in 300mm semiconductor fabs.

Simple maintenance and reduced ongoing costs

The use of patented leading-edge TDL technology provides zero drift accuracy, reducing ongoing calibration requirements, while the use of this sensing principle also helps to reduce ongoing maintenance thanks to its non-depleting nature.
