FAQ

How to realize automatic cleaning of test and analysis instruments and pipes?
For small micro pipe, tube, water tank, oil tank, pipe, tubing, comb, toothbrush, smoking gun, teapot tea, medicine bottles, cans, all kinds of various slot objects, containers, waste plastic washing and all staff are unable to extend parts cleaning.
How do you review instrument analysis?
The porosity, surface area, contact area of the liquid sample and fixed larger. (3) high thermal stability, mechanical strength, not easy broken. (4) the carrier size requirements, should be uniform and fine, which helps to improve the efficiency of the column. But the small particle will lead to lower column pressure, which is not good for operation. Generally choose 40-60 items, 60-80 items and 80-100 items.
Which analytical instrument is suitable for the determination of the gold content of gold plating bath?
Traditionally, the weight method or the iodine method is used to measure the accuracy, but the operation time is testedIf you can on the instrument analysis, proposed by X ray fluorescence and the fastest lossless, the budget can be used to atomic fluorescence by atomic absorption.12g/l this concentration. If the original ceiling may also need to dilute the sample solution. With instrument analysis and manual method
How do you understand the performance indicators of an analytical instrument: dynamic range? How do you understand the following diagram?
In the linear response limit above the measured signal, it is necessary to change the "sampling amount" and other measures, so that the measured signal in the linear range before you can calculate the results reported
An instrument for measuring the size of a building. What is it called?
Laser range finder is an instrument that uses laser to measure the distance of target accurately. The laser rangefinder emits a beam of very fine laser to the target in the job, the laser beam by the optical element receives the reflected laser beam, the timer determination time from transmitting to receiving, calculating the distance from the observer to the target. Laser range finder is light weight, small size, simple operation, fast and accurate, and its error is only 1/5 to hundreds of other optical range finder.
What is the analysis error of the carbon sulfur analyzer?
1, measuring range: C:0.02-6.00% (need to change the amount of sample) S:0.003-2.00%2, measuring time: about 45 seconds (excluding sampling, sampling time)3, the measurement accuracy conforms to the GB/T223.69-2008 standard: carbon sulfur conforms to the GB/T223.68-1997 standard.
What are the problems in the application of analytical instruments?
Analytical instruments also have limitations, such as gas chromatography can not measure a high boiling point of organic matter, the detector does not respond to the material can not be measured, the column has no adsorption ability on the target can not be measured.
Water quality analyzer, what are the well-known domestic manufacturers?
Multi parameter water quality analyzer as multi parameter water quality automatic monitoring system for integrated water monitoring, environmental monitoring stations, municipal water treatment, municipal water quality supervision and monitoring of rural tap water; circulating cooling water, pool water management, industrial water recycling, aquaculture and other fields.
