John Morris Scientific has introduced a detection solution for analytical and preparative HPLC applications: Gilson's 171 and 172 Diode Array Detectors (DAD).
Photo diode array detection collects the entire UV spectrum during the elution of a chromatographic peak.
DAD Detectors provide the 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 0.8nm/pixel for high spectral resolution.
It features a wavelength range of 190 to 610nm.
The 171 Detector features a lower spectral resolution compared with the 172 and a wavelength range of 190 to 720nm 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 one metre away from the detector.
This allows for a direct coupling of the column output to the flow cell for fast response time to 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 supported in Gilson's Trilution LC Software v2.0.
Trilution LC 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 graphically indicates peak purity and the capability for user-defined settings with automatic re-injection of a sample based on that peak-purity value.
