High-Pressure Cell System
The ISS High Pressure Cell System (HPCell) includes the Pressure Cell, the pump, and the software for system control and data acquisition. The system can be interfaced directly to ISS spectrofluorometers or utilized as a stand-alone unit with other fluorometers.

The HPCell has been specifically designed for the fluorescence and absorption studies of samples (solid and solutions in cuvettes) at pressures of up to 4,000 bar (43,500 psi). The cell features three 10mm-diameter quartz windows placed at ninety degrees for the acquisition of either L- or T-format fluorescence measurements. A 4-window cell version is available for the simultaneous acquisition of fluorescence and absorption data. Sapphire windows are also available.

The high aperture 10mm-diameter windows allow for using as an excitation light source either a laser, a light emitting diode (LED) or a collimated beam from a xenon arc lamp. The unusually high numerical aperture (NA = 0.18) for a cell makes it unique for high sensitivity fluorescence studies.

The cell fits into any of the ISS spectrofluorometers; mounting kits are available for several commercial instruments as well. If the cell does not fit into an instrument, a kit with fiber optic bundles is available for connection to the instrument.
