Star-Chrom Lite is a low cost 32 bit HPLC software package operates in Windows 95, 98, ME, and NT systems. The software can be used with any HPLC system or HPLC detector that has an analog output available for contact closures. If used with D-Star detectors and HPLC systems, the software will autozero the detector, and monitor system pressure with High-Low alarms. The software is based on the Star-Chrom HPLC Management Software, which incorporates full instrument control. Since the file system in both software packages is the same, all data acquired and processed with the low cost data systems is compatible with Star-Chrom.
