Binary Gradient HPLC Systems

The Lowest Priced Automated Variable Wavelength

The DGS-20/20P incorporates the DLC-20/20P with a second pump and the new Star-Chrom™ dual channel Windows 95, 98 and NT based software for data acquisition and instrument control.

Mixing of the solvents takes place in a precision mixing tee/pressure transducer with a minimum of dead volume. The software permits simple programming for the gradients. The two pumps are controlled via RS-232 serial ports. Detector control is accomplished via contact closures. This provides precise wavelength and absorbance range control.

The data is acquired from two detectors, if desired, where the detector is automatically controlled by the software. For both the DGS-10/11, DGS-10P/11P and the DGS-20/20P a CPU with an available COM port is required. All Star-Chrom™ systems can be operated with both standard PC's and laptops. The complete systems are priced far below any other comparable system.
