Abstract: The apparatus comprises a pump (1) for sucking the liquid (5), a filter (3) with two outlets (8 and 9), outlet (8) for draining and outlet (9) for filling the cell (12). Interferometer measurements are made at a temperature between 35° and 50 °C (fluctuation 0.2 °C) and with a maximum relative humidity of 0.2 %. Absorbance curves a(f) are determined with respect to the matrix and the concentrations of components to be assayed are calculated by means of standard equations.

Abstract: An optical gas analyzer comprising a source of radiation (1) and means (8) for conducting the radiation obtained from this source (1) through a gas sample and a number of optical filters (10a,10b,10c) corresponding to the number of gases analysed, each of which allows through a wavelength representative for the particular gas and especially absorbed by the same, to a number of detector (11a,11b,11c) corresponding to the number of gases analyzed. The gas analyzer described is intended primarily for the measurement of anaesthesia gases, e g halothane, isoflurane and enflurane, carbon dioxide and laughing gas and in particular in connection with anaesthization for monitoring the patient and administering the anaesthetic. The gas analyzer is characterized by means (8a,8b,8c) for the dividing up of the radiation path after passing of the gas sample for the purpose of simultaneous measurement of the gas concentrations in respective detectors.

Abstract: A beam of light falling within the range of 180 to 3,000 nanometers is transmitted through a flow cell (12) in an optical compartment of an absorbance detector (16) after warm up of the equipment while the eluant flows through the flow cell (12) from a chromatographic column (20). The column extends upwardly from the absorbance detector (16) into an air chamber (60) having a volume of approximately 0.25 cubic foot formed with acrylic walls. Air flows from the absorbance detector (16) under the power of a fan at approximately 10 cubic feet per minute upwardly through an air duct having a cross section of approximately 1.5 square inches to the top where it connects with the air chamber (60), the speed of the motor being adjustable until temperature varies less than one degree Celsius between the flow cell (12) and the lower 10 centimeters of the column. Under these conditions Schlieren noise from the flow cell (12) due to flow-induced thermo-optical effects is reduced.
