Agilent 8453 Diode Array Spectrophotometers
- UV-Vis spectral acquisition and analysis in less than 1 second
- Stable optics, low noise electronics, no moving parts
- Simple operation via application software
- Pre-aligned deuterium and tungsten lamps exchanged easily
- Self-test and revisions built into the software/firmware
The Agilent 8453 Spectrophotometer is an essential component in UV-Visible systems. Routine and occasional users can take advantage of the diode-array features including fast scanning, excellent sensitivity, and virtually absolute wavelength reproducibility.
Featuring exceptional ruggedness and reliability, this Agilent spectrophotometer is easy to use with a line power indicator, a status indicator and other push buttons. This equipment uses a photodiode array (PDA) which highly reliable. Simultaneous measurements of the complete light spectrum take less than a second using this array. Effective data analysis and archival with the use of data analysis software software ensures compliance with good laboratory practices (GLP) and pharmacopoeia requirements.
Offering minimum maintenance and an open sample area, the Agilent 8453 Diode Array Spectrophotometer has excellent optical performance. Unlike conventional instruments, the Agilent 8453 is not weighed down by ambient stray light.
