Experimental testing of the digital multichannel analyzer for gamma spectrometry measurements

Multichannel processing for airborne gamma-ray spectrometry

The conventional approach to the processing of airborne gamma-ray spectrometric data is to first sum the observed spectra over three relatively broad energy windows. These three window count rates are then processed to obtain estimates of the potassium (K), uranium (U), and thorium (Th) elemental abundances. However, multichannel spectra contain additional information on the concentrations of K...

Can We Apply the Control Material from Standard Clinical Chemistry Analyzer for Usage in the Point of Care Testing Analyzer?

The Multichannel Analyzer

The multichannel analyzer (MCA) is an important laboratory instrument which can measure distributions of input signals consisting of pulses. It operates in two different modes: pulse height analyzer (PHA) mode, and multichannel scaler (MCS) mode. In PHA mode, the input pulses are sorted into bins (channels) according to their amplitude, while in MCS mode they are sorted according to the time wh...

Producing 65Zn and 60Co gamma sources for energy and efficiency calibration of gamma spectrometry systems

Precise calibration of energy and efficiency of gamma spectrometry systems for different geometries is very important. In most cases, preparation of these sources for educational and research centers  is very difficult due to high costs and lack of access to the reactor. The purpose of this paper is to explain the procedure for production of calibration sources 65Zn and 60Co using instrumental ...

A multichannel continuous-flow analyzer.

A 10-channel analyzer is described with which sodium, potassium, chloride, carbon dioxide, calcium, phosphorus, total protein, albumin, albumin blank, and uric acid levels may be determined simultaneously. Operating at the rate of 60 specimens per hour, the instrument uses less than 1 ml. of serum for all 10 determinations. The results appear on 5 two-pen recorders. The report describes the ins...
