Analytical performance characteristics

An ideal analytical method should be: simultaneous determination of multiple components; determination of the width of the sample (low and high content components can be measured); with high sensitivity and good accuracy; can be applied to samples of different states Analysis; operations are simple and easy to master. The HK-8100 Inductively Coupled Plasma Emission Spectrometer (ICP-AES) analysis method has these excellent analytical properties:

(1) HK-8100

The ICP-AES method is first of all an emission spectrum analysis method, which can be simultaneously determined by multiple elements.

As long as the atom to be tested is in an excited state, the emission spectrum analysis method can simultaneously emit the respective characteristic lines and simultaneously perform the measurement. The HK-8100 ICP-AES instrument is a single-channel scanning instrument that can simultaneously measure a large number of elements in the same sample solution. Except for He, Ne, Ar, Kr, Xe inert gases, c, H, O, N, S, most of the elements can be measured. Of course, in practical applications, not all elements can be conveniently measured by the ICP-AES method, and some elements are determined by the ICP-AES method, which is more effective than other analytical methods. Nevertheless, the ICP-AES method is still the most effective method for elemental analysis.

The light source is a light source with a small self-priming phenomenon. The linear range of the calibration curve of the HK-8100 ICP-AES method can reach 5 to 6 orders of magnitude, that is, the content of 0.00n% to n0% can be simultaneously measured. In most cases, the elemental concentration is simply linear with the measured signal. It can measure low-concentration components (below mg/L) and simultaneously measure high-concentration components (hundreds or thousands of mg/L).

(3) ICP-AES

The method has high evaporation, atomization and excitation ability, and is electrodeless discharge without electrode contamination. Due to the abnormal high temperature of the plasma source (the torch is up to 10,000 degrees and the sample area is also above 6000 °C), the chemical interference and matrix interference of the general analysis method can be avoided, and the interference level is lower than other spectral analysis methods. The plasma torch has a higher temperature than a general chemical flame, and can atomize and excite elements that are difficult to be excited by a general chemical flame, so that it is advantageous for the measurement of difficult-to-excite elements. Further, it is difficult to form a refractory metal oxide in an Ar atmosphere, so that the effects of the matrix effect and the coexisting element become inconspicuous. Many can be directly measured to make the analysis operation simple and practical.

The method has the stability and measurement accuracy of the solution injection analysis method, and the analysis precision can be compared with the wet chemical method. The detection limit is very good. The detection limit of many elements is less than 1mg/L (1ppm). The HK-8100 ICP-AES instrument can measure 1.5% or less when the RSD performance is good, and some short-term accuracy is 1% RSD. . HK-8100 ICP-AES is a solution analysis method that can be calibrated with standard materials and is traceable.

The HK-8100 ICP-AES instrument is accurate, simple, easy to use, and has an extremely high analysis speed. Paying more attention to the needs and efficiency of the actual work, the user does not need to spend time and effort on the adjustment of the instrument, so that more energy can be put into the analysis and measurement work, making the ICP an easy-to-use, versatile utility.

Injection technology for ICP-AES analysis

HK-8100ICP-AES

The injection technique is a liquid atomization injection.

Simply dissolve the sample to make a solution of a certain concentration. By dissolving the solution into a solution and analyzing it, not only the structural interference and non-uniformity of the sample can be eliminated, but also the preparation of the standard sample is facilitated. More than 15 elements can be measured in less than 1 minute. Moreover, automatic measurement has been achieved. The number of measurable elements is probably more than any similar analysis

There must be more laws, and it is certain that there is no simultaneous analysis method that can match it.

In the application of the method, the operation of the instrument is much simpler, but the pretreatment of the sample is very important and critical. If the sample processing is not completely clear, the precision of the instrument is also no good.
