Agilent Cary 7000 UV-Vis-NIR Grating Spectrophotometer
Description
n 2013, ODA was the first US company to acquire the Agilent Universal Measurement Accessory [UMA]. which converts the Agilent Cary 5000 UV-Vis-NIR SPM described below into the Agilent Cary 7000 system. ODA was involved in the development of the system during two visits to the factory in Melbourne, Australia and served as a beta site for the system prototype. The system employs a highly automated concentric rotary table with an accuracy of 0.02° that is cantilevered from the sample compartment. The sample is mounted on the inner ring and can be rotated to any angle; the detector arm can rotate to almost any angle, except where it would block the beam, on the outer ring. A wire grid polarizer on a separate rotator provides automatic beam control for s, p, or any intermediate polarization state. The detector is silicon/InGaAs element hybrid with a range of 250 to 2500 nm with the polarizer and 200 to 2800 nm without it. The Cary 5000 is a double-beam, double-grating SPM with a 0.2 < λ < 3.30 µm range. This instrument is considered the state-of-the-art in commercially available SPMs; it was introduced in 2003 and one was acquired by ODA in 2004. The standard sources are deuterium and tungsten-halogen lamps, but mercury and other lamps can be substituted in the source turret. Its monochromator is driven by a stepping motor for accurate normalization and background subtraction. The instrument self-calibrates in wavelength on every initialization with its deuterium lamp. The sample compartment is large and flexible. The detectors are a UV-enhanced PMT and a cooled PbS cell.
