Abstract: A modular probe is provided to enable introduction of light to a sample to be analyzed by an electro-optical device. The probe of the present invention may include an optical rod or other device for propagating light, an optical barrel which in part surrounds the optical rod, and a sleeve which is provided to attach the probe to a source of light such as a fiber optical bundle. The probe may be fitted with a bidirectional focusing adapter and a reflective tip. A transverse probe is also described.

Abstract: A modular flow-through cell is described which has main block member having a first pathway which leads from an inlet port to a large bore and a second passageway which leads from the large bore to an outlet port. A cartridge assembly is removably inserted into the large bore to provide an optical path for light to pass through a fluid sample.
Abstract: The invention is a multiplexer which enables light to be sent to and received from samples for simultaneous analysis. A multiplexer is described which uses a transverse probe to reflect light at an angle into an optical rod. The transverse probe is selectively rotated to transmit light to a second optical rod. Various numbers of optical rods may be used in the linear mutliplexer. A multiplexer is also described in which a conjugate optical barrel is utilized to selectively reflect light to various probes.

Abstract: A purge module is provided which provides gas to an enclosure at a first flow rate in order to purge the enclosure of harmful gases. After the pressure within the enclosure has reached a predetermined level, a sensor enables gas at a low pressure to be supplied to the enclosure after a predetermined time has passed. The purge module also enables power to be supplied to the device being purged at the same time the purge gas flow rate is changed.
