Improvement of accuracy for the determination of transient signals using the Kalman filter. Part 2. Computer controlled batch hydride generator with data acquisition and Kalman filtering for noise reduction

Abstract

The design and operation of a computer controlled batch hydride generator is described. All operations in the analytical procedure are controlled from the keyboard of the computer. Data are collected and stored by the computer and retrieved and manipulated by the Kalman Filter to remove white noise and, hence, determine the signal under the noise. A comparison between measurements using peak height determination and the Kalman filter shows similar detection limits. It is shown that a signal buried in the noise, at a ratio of almost 1:4, can be detected. Germanium was used as the test element.
