QC samples are generally used to check whether your curve is standardized or not, he is a known concentration of the sample and the concentration has a positive or negative error, for example, 3.240 ± 0.012 mg / l. You will bring him into your curve to see if the data are within the error range of the concentration, if it is within the range, it can show that your curve. You will bring him into your curve to analyze, to see whether the data in the quality control sample concentration error range, if within the range, it can show that your curve is not a problem, the corresponding other data are also correct. The standard substance, also a known concentration of the sample, but his concentration is generally an integer, such as 1000 μg / liter, is used to configure the standard curve to use
In the international standard substances and standard samples in the English name for "Reference Materials", by the ISO / REMCO organization responsible for this work. REMCO organization responsible for this work. In China, the measurement system will be "Reference Materials" called "standard substances", while the standardization system called "standard samples". In fact, there are many similarities between the two, but also some minor differences
