Thermo Fisher iCAPQ calibration solution is mainly used for calibrating and tuning the iCAPQ series inductively coupled plasma mass spectrometer (ICP-MS) to ensure stable instrument performance and accurate and reliable measurement results. Here are its specific uses:
Calibration instrument quality axis: The calibration solution contains specific ions of known mass. By introducing the calibration solution into the instrument, the instrument will calibrate its quality axis based on these known mass ions, ensuring that the instrument can accurately identify and measure the mass of different ions. For example, the calibration solution may contain ions of elements such as lithium, indium, rhodium, etc. The mass of these ions is known, and the instrument adjusts its mass measurement system by detecting and analyzing these ions to make its measurement results consistent with the known mass.
Optimize instrument sensitivity: The sensitivity of different elements in ICP-MS may vary, and calibration solutions can be used to optimize the instrument's sensitivity to various elements. By adjusting the parameters of the instrument, such as RF power, atomizer flow rate, plasma temperature, etc., the detection signal of each element in the calibration solution can be optimized, thereby improving the sensitivity of the instrument to detect various elements in the sample.
The linear range of the calibration instrument: The linear range of ICP-MS refers to the range of element concentrations that the instrument can accurately measure. Calibration solution can be used to calibrate the linear range of instruments. By measuring with different concentrations of calibration solution, the calibration curve of the instrument can be drawn to ensure that the instrument can accurately measure the elemental content in the sample at different concentrations.
Stability of the testing instrument: Regularly using calibration solution to test the instrument can evaluate its stability. If the measurement results of the instrument deviate significantly from the expected values of the calibration solution over a period of time, it indicates that there may be a problem with the stability of the instrument and further inspection and maintenance are needed.
Ensure the accuracy of analysis results: By using calibration solution to calibrate and tune the instrument, instrument errors can be reduced, and the accuracy and reliability of analysis results can be improved. This is crucial for laboratories in fields such as scientific research, environmental monitoring, and food and drug safety testing, as it ensures the accuracy and reproducibility of experimental data.
