John Morris Scientific has introduced a new detection solution for analytical and preparative HPLC applications, Gilson’s 171 and 172 Diode Array Detectors (DAD).
Photo diode array detection allows collection of the entire UV spectrum during the elution of a chromatographic peak.
DAD Detectors provide the full power of simultaneous multiple wavelength detection and spectral information with high resolution and sensitivity.
The 171/172 Detectors allow for simultaneous acquisition of up to eight compound specific wavelengths for enhanced sensitivity.
The 172 Detector features 512 pixels with a pixel distance of 0.8 nm/pixel for high spectral resolution and a wavelength range of 190 to 610 nm.
The 171 Detector features a lower spectral resolution in comparison to the 172 and a wavelength range of 190 to 720 nm at an economical price.
Both the 171/172 Detectors feature remote light fibre technology.
Using fibre optic cables for the light path allows for an optional remote flow cell that can be positioned up to 1 meter away from the detector.
This allows for almost a direct coupling of the column output to the flow cell for fast response time to better ensure accurate collection of the analytes of interest.
An interchangeable flow cell design accommodates micro bore to preparative applications.
The 171/172 Diode Array Detectors are fully supported in Gilson’s Trilution LC Software v2.0.
Gilson’s Trilution LC Software v2.0 features spectral library creation, 3D and Iso-electric plots as well as spectrum and peak purity.
The peak purity function in LC v2.0 provides graphical indication of peak purity and the capability for user-defined settings with automatic re-injection of a sample based on that peak purity value.
