CLINICAL CHEMISTRY, Vol. 18, No. 7, 1972 671 In the continuous-flow automated system described _____________ _ __ ______ here, we used components from several manufacturers, grouped to provide satisfactory performance at low cost. The IL Model 143 flame photometer is simple to maintain, the burner is mounted externally and is transparent, so that it can be inspected without interrupting operati...

Microlens array homogenizers are an attractive choice in the field of radiometry and photometry to generate highly uniform beams with high efficiency. In the present paper a microlens array homogenizer used to determine the spectral responsivity of large size, partially filtered photometer is presented. The effect of nonuniformity of the field is shown to be smaller than 0.2% in the whole visib...

An Eppendorf flame photometer may be used to estimate sodium, potassium, and calcium in plasma which has been automatically sampled and diluted. Readings may be automatically recorded by feeding the output from the photomultiplier into a sensitive recorder. This method estimates 60 samples an hour, using approximately 0.12 ml. plasma per estimation. The accuracy of the method is discussed.

lithum can be de termined both by atomic absorption spectroscopy andflame emission spectroscopy. we have used the later method with a zeiss model pmqli spectro photometer fitt ed with ante-chamber atomizer and a potensiome rric line recorder. accurate ana lysis for the clement was acco mplished due to a sophisracared measuring instrument.

In this paper, we present the obtained first scientific results from CSIR-NLC mobile LIDAR (LIght Detection And Ranging) and its validation/comparison with other ground and space-borne measurements. The LIDAR results are compared using aerosol measurements from the Stratosphere Aerosol Gas Experiment (SAGE) and Optical depth derived from sun-photometer employed under AErosol RObotic NETwork (AE...
