3 Terms and definitions

The terms and definitions defined in GB/T 32267, JJG1151 and the following apply to this document.

3.1 Baseline drift

A slow change in the baseline under specified operating conditions and over a specified period of time.

[Source. GB/T 32267-2015, 2.20]

3.2 Resolution

The degree of separation between two adjacent chromatographic peaks is the difference in retention time of the two components divided by their average peak width.

[Source. GB/T 32267-2015, 7.47, modified]

3.3 Long-term stability

The stability of the results of continuous measurements of the same sample by the instrument at different time periods over a longer period of time within a specified time.

Note. It is generally expressed as the combined relative standard deviation of the measured value results.

[Source. GB/T 32267-2015, 6.30]

4 Reagents and Materials

4.1 Hydrochloric acid (HCl). high-grade pure.

4.2 Nitric acid (HNO3). high purity.
