Features:

• Select the items to implement during inspection to confirm the approximate time required for full inspection.
• The system is capable of both wavelength repeatability checks and wavelength accuracy checks using a wavelength calibration filter. If the optional mercury lamp unit is used, wavelength accuracy can be inspected using the low-pressure mercury lamp's bright line.
• The software is capable of resolution inspections using methods defined in the EP (European Pharmacopoeia) and USP (United States Pharmacopoeia) as well as the method for checking the bright line spectral bandwidth.
