Detector Features

Page 32
The device comprises the following main features:
• A deuterium lamp for ultraviolet (UV) and visible (VIS) wavelength
detection as the light source of the device
The deuterium lamp provides light for the complete wavelength
detection range from 190 nm to 680 nm.
• Fused-silica LightPipe™ flow cells for minimum noise and peak
broadening
• Internal validation of the wavelength accuracy with holmium oxide
glass filter
• Variable slit width, settable to 1, 2, 4 or 8 nm, to optimize baseline
noise and optical resolution
• For data collection, the device supports the following features:
Data collection rate up to 200 Hz
¨
Acquiring 3D data fields (spectra) to record all wavelengths
¨
simultaneously
Among other things, 3D spectra make peak purity analysis and
spectral library search for peak identification possible.
Recording of up to 10 signal channels at individual
¨
wavelengths (2D data)
• Identification (ID) chip on the deuterium lamp and the flow cell
• Thermal control using heaters for the optics and a cooling fan for the
lamp house
• Motorized filter paddle (shutter) to move into the light path before
the flow cell
The filter paddle can move into the following positions:
Open position for data acquisition
¨
Closed (dark) position for protection of the flow cell
¨
Holmium oxide filter position for validation of wavelength
