More wavelengths or a scan are used in liquid chromatography to verify the purity of analyzed samples or in situations when some peaks absorb on different wavelengths. Thanks a new miniature deuterium lamp has the unit surprisingly small dimensions.
The unit is supplied with an AMY17 PCB board of dimensions 100 x 160 mm (3.94 x 6.30 in). It powers the lamps and controls the unit. Thanks to new board features it allows the sending of spectra with high resolution and speed up to 20 Hz depending on baud rate.
AMY17 board allows to have optional extension modules (for additional cost):
• Analog outputs board
• LAN and USB board
• Display with keyboard
• Leakage sensor
The most important features of the BABY18DAD detectors:
• small dimensions
• built-in lamp working hours counter
• easy replacement of flow cell
• measuring at more wavelengths simultaneously
• sophisticated diagnostic software
