Completely new scanning and multi wavelength UV detector incorporates functions normally associated with photo diode array detectors
The development of a completely new scanning and multi wavelength UV detector has been announced by Cecil Instruments.
The company designed and produced the world's first commercially available variable wavelength UV detector for HPLC in 1971 and has now developed the first ultra-fast UV scanning detector enabling full UV range scans in about 200 milliseconds.
The new CE4300 dynamic absorbance detector incorporates functions normally associated with photo diode array detectors while offering users improved performance when used for single or multi wavelength detection.
Significant cost savings when compared with PDA detector based systems are achieved.
Standard functions of the CE4300 dynamic absorbance detector include: 'Lambda Max' scans of peaks to determine optimum monitoring wavelengths for variable wavelength detection.
Peak purity checks by normalised overlaying of known stored scans.
Peak impurity checks by overlay of normalised upside and downside wavelength scans of peaks.
Identification of unfamiliar peaks by comparison with selected library spectra.
Identification of peaks by comparison with stored scans of known samples.
Wavelength scans of peaks less than 1.4 seconds wide.
Stores up to 100 wavelength scans for any single elution, in buffer store.
Stores to up 100 wavelength scans in safe memory password protected.
Optical bandwidth 4nm.
UV scans in only 200msec.
Up to eight wavelength scans of a single eluting peak.
Noise as variable wavelength monitor +/-0.5 x 10-5 AU.
Drift as variable wavelength monitor +/-3x10-5 AU/hour.
Performance as for diode array detector.
Top performance as a variable wavelength detector.
Dual wavelength operation.
Up to four wavelength programme operation.
