Warning - Personnel using this document shall have formal laboratory work
experience. This document does not point out all possible safety issues. Users are
responsible for taking appropriate safety and health measures and ensuring that
the conditions stipulated by relevant national laws and regulations are met.
1 Scope
This document specifies the determination of aluminum, calcium, magnesium,
manganese, phosphorus, silicon, titanium content by inductively coupled plasma
emission spectrometry.
2 Normative references
The contents of the following documents constitute the essential terms of this document
through normative references in the text. Among them, for dated references, only the
version corresponding to that date applies to this document; for undated references, the
5.5 Hydrochloric acid, 1 + 1.
The calibration solution is the solution required for drawing the calibration curve of the
analyzed elements. Its concentration range in the solution is expressed in micrograms
per milliliter, which depends on the performance parameters and linear sensitivity of
the instrument. At least 10 solutions are required to cover the measurement range (mass
fraction) shown in Table 1.
8.4 Determination
The ICP spectrometer shall first be initially adjusted, according to the manufacturer's
recommendations and laboratory quantitative analysis operations.
Try to optimize the instrument parameters in each round as much as possible.
9.3 Standardization of calibration curve (drift correction)
The regular inspection and correction of the calibration curve shall be carried out as
follows.
Take two calibration solutions, namely the one with the lowest and highest analyte
content.
In the drawn calibration curve, the intensities of the two calibration solutions are
measured; the correction coefficients α and β are calculated according to formulas (4)
and (5).
