Abstract: A hand-held combined spectrophotometer and gloss meter quickly and effectively measures the appearance of a color sample. Light generated by a krypton-filled tungsten bulb shines on the sample and is reflected at 45.degree. into twenty-one photodiodes spaced at staggered intervals around the sample stage. A diffuser in the light path reflects a portion of the light back onto a pair of red and blue sensitive reference photodiodes. The output of the red and blue reference diodes compensates for changes in the output of the bulb. An LED produces light which shines on the color sample at an angle of 30.degree.. The reflected light is received by a large-area photodetector which determines the gloss of the sample. A viewing port permits the user to view the sample prior to measurement. When the viewing port door is opened, it automatically actuates the light and illuminates the sample for viewing. The viewing port door is automatically closed by a return spring. The instrument can be hand-held and operated by buttons on the front or a redundant button on the back. The operator may choose between a simple pass/fail appearance indication or can obtain more detailed information from an LCD display. The instrument may also be mounted for lab use and connected to exterior peripherals such as printers and the like.

Abstract: A method and apparatus for automatically determining the amount of a hemoglobin species in a blood sample in relation to the total amount of hemoglobin in a blood sample by simultaneously determining the relative concentrations of the two samples with a spectrophotometer. The spectrophotometer has two channels each of which is associated with one sample. Each channel determines the intensity of light from a light source which is transmitted through its sample and received by a photodetector. Thereafter, the apparatus calculates the relative concentration of the two samples (A.sub.1 /A.sub.2) or optionally the normalized concentration of the samples (A.sub.1 /A.sub.1 +A.sub.2). The apparatus includes automatic self-calibration to compensate for any degradation of the optical system.

Abstract: A spectrophotometer includes: a sample-chamber lid capable of opening and closing an opening portion of a sample chamber for setting a sample and a reference sample; and sample-chamber lid opening-closing detecting means for detecting an opening-closing state of the sample-chamber lid, and the spectrophotometer is capable of controlling a measurement of a xenon flash tube as a light source, a spectroscope, a detector, an amplifier, an AD converter, a processor, a storage device, and a data display part. In the spectrophotometer, the light source is turned on after a state of the lid changing from an opening state to a closing state is detected in a sample-setting instruction state by the sample-chamber lid opening-closing detecting means; absorbancy, transmissivity, reflectivity, a sample-side energy value, or a reference-side energy value is measured; and a measurement result is displayed on the data display part.

Abstract: An instrument for quantitative analysis includes two shutters, one of which prevents light from being introduced into a black box housing a cell holder from the outside through a port in which a cell may be placed in and taken out the black box, and the other of which prevents light from impinging on a photomultiplier tube which is in communication with the black box. The shutters are controlled by a control unit so that one of the shutters opens when the other closes. The instrument also includes detectors which detect whether or not the cell holder and the cell are disposed at predetermined positions, respectively. The detectors output signals to the control unit. The control unit controls an automatic pipetting device to restrict a sample from being introduced into the cell when both the cell holder and the cell are not disposed at the predetermined position.

Abstract: A chemiluminescence analyzer determines the level of chemiluminescence of a specimen. The chemiluminescence analyzer includes a light detection chamber for containing the specimen to be analyzed. The light detection chamber includes a chamber access device, for allowing the positioning of the specimen within the light detection chamber, and a shutter device. The shutter device and the chamber access device are configured to each have an open position and a closed position. A light detector is positioned behind the shutter device. When the shutter device is in the open position, the light detector detects light within the light detection chamber. An interlock assembly is interfaced with the shutter device and the chamber access device, such that the interlock assembly prevents the shutter device and the chamber access device from being simultaneously opened.
