Automatic compensation for baseline and peak fluctuations is achieved with patented electrical and auto-zero design. With a user-friendly keypad and LCD display, the LC1246k continuously monitors signal output and provides immediate visual feedback on detector performance and operation. For unattended operation, all detector controls can be interfaced with your integrator or data station.

LC1255s Programmable Scanning Fluorescence Detector

A high sensitivity scanning fluorescence detector for fluorescence, phosphorescence and chemiluminescence, the LC1255s uses high-efficiency holographic diffraction gratings optimised for high sensitivity at both lower and higher excitation wavelengths. Selectivity can be adjusted with selectable slit widths. The pulsed xenon lamp provides a high energy level across the UV/Vis spectrum 200 - 600 nm (200 - 900 nm Option) and produces no harmful ozone. A wide dynamic range is made possible by 20-bit digital electronics. Time programming of both excitation and emission wavelengths allows optimised sensitivity and selectivity, while automatic real-time scanning of eluting peaks helps identify optimum wavelengths. Up to sixty spectra may be stored for display on the LCD display or played back to an external collection system. Pre-aligned lamp and flowcell simplifies operation.
LC1260
Add LCEC capability to your existing HPLC system without major instrument re-configurations or user re-training. The LC1260 electrochemical detector provides enhanced detector performance in a robust and easy to use instrument. It adopts a patented Wall Jet Flowcell design optimised for high assay sensitivity, wide linear dynamic range, response stability and reproducibility.

In LCEC the electrode surface is in direct contact with the test medium, resulting in gradual fouling of the electrode surface due to the adsorption of chemicals. The washing effect of the impinging jet made possible by the wall jet design improves electrode stability and precision with much-reduced down-time for electrode cleaning. The design also enables faster warm-up and equilibration. The detector utilises a modular, stackable design and can be readily integrated into existing HPLC systems.

LC1460
For reliable solvent conditioning for both isocratic and gradient applications, the LC1460 provides four channel on-line removal of interfering gases, particularly oxygen, ensuring continuous stable operation for high quality assay results. Dissolved gases are removed from the mobile phases as the solvents travel through tubular gas-permeable membranes within the degasser's compact vacuum chamber. Channels can be serially connected for further enhancement of the degassing efficiency for trace level analysis.

The degasser allows non-stop unattended operation for higher laboratory productivity. Improved detection limits and baseline stability for UV, fluorescence and refractive index detection, improved pump flow performance, and the elimination of expensive helium sparging are some of the benefits.
