Continuous Flow Autoanalyzer
To give 100% assurance to the clients, we are engaged in manufacturing and supplying of an exclusive range Auto Analyzer. These analyzers are used as automated industrial analyzer which uses continuous flow analysis technique. Our well expert personnel team manufactures these analyzers making use of quality grade materials and components sourced from the authentic vendors. The quality inspectors check the Auto Analyzer on durability and efficiency parameters before offering to the clients at reasonable price.
AutoAnalyzer is an automated analyzer using a special flow technique named "continuous flow analysis (CFA)" first made by the Technicon Corporation.
The AutoAnalyzer profoundly changed the character of the chemical testing laboratory by allowing significant increases in the numbers of samples that could be processed. The novel design based on separating a continuously flowing stream with air bubbles all but eliminated slow, clumsy, and error prone manual methods of analysis. This instrument single handedly changed the concept of days per sample to a mindset that hundreds, or even thousands, of tests are possible per day.
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. The tubing passes the samples from one apparatus to the other with each apparatus performing different functions, such as distillation, dialysis, extraction, ion exchange, heating, incubation, and subsequent recording of a signal. 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. The air bubbles also assist mixing by creating turbulent flow (bolus flow), and provide operators with a quick and easy check of the flow characteristics of the liquid. 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, however, since the presence of bubbles create an almost square wave profile, bringing the system to steady state does not significantly decrease throughput (third generation CFA analyzers average 90 or more samples per hour) and is desirable in that steady state signals (chemical equilibrium) are more accurate and reproducible.
A continuous flow analyzer (CFA) consists of different modules including a sampler, pump, mixing coils, optional sample treatments (dialysis, distillation, heating, etc), a detector, and data generator. Most continuous flow analyzers depend on color reactions using a flow through colorimeter, however, many methods have been developed that use ISE, flame photometry, ICAP, fluorometry, and so forth.
