Introduction
A trace element according to the different needs of the user groups designed analyzer. Some users are more determined detection range . Only for zinc copper and iron , calcium and magnesium five elements, but the instrument calling for lower prices and consumption costs . DS-3A ( single channel 5 element type) trace element analyzer main set for these users . Features 1. Samples categories: whole blood (20 microlitre) or hair (0.1 grams). 2. The test items: conventional zinc, copper, iron, calcium, magnesium, can add project according to customer's demand. 3. The technical features: trace element detector adopts single electrode (static mercury electrode) system, polarography measuring blood zinc in accord with the ministry of health inspection procedures, etc. Less dosage of samples, less reagent consumption and low detection cost. Calibration instrument with whole blood standard substances, results are accurate, instrument repeatability, stable performance, high reliability results. 4. Use the unit under the county hospital, maternal and child health care, in towns and townships, community hospitals and clinics. 5. The instrument features: low prices, superior performance and beautiful appearance, especially suitable for small medical institutions. Technical parameters: 1 , the electrode is equipped with : static mercury drop electrode (patent products).
2 , analysis methods and functions: potential polarographic function, VA polarographic function.
3. Applications: whole blood ( or hair) detection of zinc, iron , copper , calcium, magnesium
4, the detection limit : 10 micrograms / liter ( to measure zinc as an example)
5 , the coefficient of variation : RSD≤5%
6 , correlation coefficient : ≥0.99
7, the calibration curve relative deviation : ≤10% ( to measure lead , for example)
8 , first restore the ability of anti : 5000: l
9 , detection methods: polarography measured zinc, iron , calcium , magnesium, copper.
