Liquid Chromatograph For Sale

Liquid chromatograph

A liquid chromatograph is a medical device used for separation of the mixture under study into liquid stationary phase and mobile phase with the help of passing its components under high pressure through slurry adsorbent. The method allows separating the needed particles from the mixture for studying or preservation.
There exist several types of chromatography:

• ion;
• exclusion;
• normal phase;
• reversed phase;
• ion-exchange.

Regardless of the type of liquid chromatography, the construction of the devices is approximately the same. The main constructional elements are a pump, a high-precision dosage unit, a column with built-in adsorbent, a recording unit and a detector. The last one is the key for the operation of the device as it determines, which particles the device works with.
There exist several types of detectors:

• mass-spectrometric;
• photometric;
• electrochemical;
• spectrometric;
• amperometric;
• refractometric;
• for charged aerosol;
• ELSD/ELLSD.

Tips and Guidelines for Buying an Amino Acid Analyzer

Primary and secondary amino acids in physiologic fluids are detected and measured by this automated analyzer, utilizing ion-exchange or reversed-phase high pressure liquid chromatography techniques. In clinical use it is also possible to monitor treatment of genetically produced disorders in protein metabolism.

Tips for Buying an Amino Acid Analyzer

1. Automated features should be a factor for facilities considering the purchase of amino acid analyzers. Some automatic features can best facilitate sample analysis, and automatic sample injection is preferred to manual injection.

2. It is best if the clinical laboratory HPLC amino acid analyzers can interface with a laboratory information system for easier collection and reporting diagnostic test results. Displaying results and other data should be available both on a monitor and as a printout.

3. Rustproof material should make up the sample amino acid analyzer's column, to ensure greater life expectancy. The column should generally be 10-150 cm long and 2-5 mm wide.

4. When using an amino acid analyzer, to ensure sufficient separation of the sample, the particle size should be as uniform as possible. The following pumps are generally acceptable: dual piston, single-piston, and syringe eluent pumps. Pumps should have a pressure limit of at least 2,000 psi.

5. Facilities need to assess the HPLC amino acid analyzers in their own clinical environment for a few weeks before making a purchase. On-site evaluation allows laboratories to test the qualities of the amino acid analyzer instrument, as reported by the manufacturer with the workload and sample types they normally handle.

6. Facilities should prefer amino acid analyzer devices that diminish the risk of infection involved with handling any body-fluid specimen, by minimizing operator contact with specimens.

7. Procedures may become more complex and sophisticated in certain situations when purchasing or upgrading an amino acid analyzer device. Implications may include additional staff training and certification, as well as changes in quality control, proficiency testing, quality assurance programs, and other laboratory procedures. 

8. Computer interface capability is another significant factor to keep in mind. The effectiveness of the HPLC amino acid analyzer interface with the existing laboratory information system or the facility's central computer system, is extremely important for inputting test data and verifying testing accuracy.
