- Model LC-D Series - Residual Gas Analyzer



The LC-D Series Residual Gas Analyzer (RGA) offers outstanding performance, yet is priced to be the most cost-effective RGA on the market. The LC-D Series instruments are constructed from materials that are compatible with Ultra High Vacuum (UHV) systems and are designed to require the very minimum in maintenance. This versatile RGA is ideally suited for use with UHV systems and equipment monitoring of semiconductor and thin film processes in the high vacuum range. Coupled with the System 2000 software (which is 32-bit, multi-threaded, and designed for use with Windows 98 through Windows 8), the LC-D provides advanced features that are associated with higher priced instruments.

The LC-D Series RGA includes Dycor’s 1-100 AMU-range open ion source analyzer head with dual filaments and Faraday cup detector, electrometer preamplifier, and RF power supply with an Ethernet port for interfacing to a PC. Options include 1-200 AMU range and 1-300 AMU range, and channel plate electron multiplier.
