Automated chemistry analyzers are a reliable and economical choice for modern laboratories. There are advanced clinical chemistry analyzers that can be used in small as well as very high volume laboratories. Available in benchtop, floor and point-of-care handheld models, these analyzers are invaluable to test for electrolytes, enzymes and proteins in samples of serum, plasma, urine, cerebrospinal fluid, and other body fluids.
These automated chemistry systems can:
- Increase the number of tests performed by one individual in a given time period (short turn around time) and thus speeds up the result
- Eliminate the potential errors of manual analysis such as volumetric pipetting steps, calculation of results, and transcription of results, thus human error is reduced
- Reduce consumables, as these instruments use very small amounts of samples and reagents, subsequently allowing less blood to be drawn from each patient
- Improve operator safety by reducing the need for chemical handling
However sample throughput and turnaround time (TAT) of automated systems vary with the size and capability of analyzers and the complexity of the assay mix and test volume. Reputable vendors also offer recertified models of these analyzers.
Quality analyzer models that leading lab equipment dealers offer include:
- Medica EASYRA – This bench top analyzer offers a maximum throughput of 150 tests/hr, 24 sample positions and 24 reagents onboard. Unlike barcodes, the new wireless RFID technology in this new random access device located in each wedge label contains all reagent information.
- Olympus AU400 – This analyzer features a standardization design which helps to maximize productivity and minimize operating costs. Ideal for routine, STAT, urine and homogenous immunoassays, the instrument uses the same reagents and user interface as larger systems.
- Roche Hitachi 912 – Equipped with standardized technology, it features automated sample handling with about 70 positions for routine, STAT and QC samples with 2-35 ml sample volumes. The product can consolidate multiple sample types including serum, plasma, urine and spinal fluid.
Advanced clinical chemistry analyzers feature automated discrete analysis which allows for an almost unlimited mix of analyses on a single instrument, including routine clinical chemistry and immunoassay tests. They perform tests on samples kept in discrete containers in contrast to a continuous flow analyzer and enable fast, flexible and precise measurements.
When choosing a clinical analyzer, consider certain factors such as the instrument’s throughput capability, testing speed and test menu, batch, whether random or continuous analysis, if additional testing is offered, and also footprint. Bar-code handling and data management software will also be required if your laboratory handles thousands of tests per hour. Make sure that the lab equipment supplier can also ensure timely supply of reagents and consumables.
