Micromechanical slit system in HPLC diode-array detection

The remarkable performance of the micromechanical slit device makes it possible to equip diode-array detectors with adjustable entrance slits. The device combines the required optical functions, i.e., slit and shutter, in a simple, reliable and compact component. The slit width is directly controlled by the microprocessor of the instrument and can be set as method parameter. It is used in the HP1100 Series HPLC Diode-Array Detector.
