    Description

    The AutoAnalyzer is an automated analyzer using a flow technique called continuous flow analysis (CFA). The design is based on separating a continuously flowing stream with air bubbles.

    Principle

    In continuous flow analysis (CFA) a continuous stream of material is divided by air bubbles into discrete segments in which chemical reactions occur. The continuous stream of liquid samples and reagents are combined and transported in tubing and mixing coils. An essential principle of the system is the introduction of air bubbles. The air bubbles segment each sample into discrete packets and act as a barrier between packets to prevent cross contamination as they travel down the length of the tubing. Samples and standards are treated in an exactly identical manner as they travel the length of the tubing, eliminating the necessity of a steady state signal. Continuous flow analyzer depends on color reactions with the principle of colorimetry using a flow through photometer.
