Q & A

What is the purpose of the tutorial in the provided transcript?

The tutorial explains how to use the JVC software and instrument for assessing potassium levels in samples using a specific analysis method (AAS JBC 93 12).

What is the first step in using the JVC software for analysis?

The first step is to ensure that the correct lamp is installed in the instrument, corresponding to the element to be analyzed (in this case, potassium).

How do you select the analysis method in the JVC software?

To select the analysis method, you need to choose the appropriate element (e.g., potassium) in the software, adjust the wavelength, and set up the instrument properties such as integration time and mode.

What is the significance of calibration in the analysis process?

Calibration is crucial as it ensures the accuracy of the analysis by creating a standard curve using known concentrations. The method used is linear least squares, and the R-squared value must be above 0.95 for accurate results.

How do you set up the calibration standards in the JVC software?

You set up the calibration standards by defining their concentrations, such as 0.1, 0.2, 0.5, 1, and 2 mg/L, within the software, and then adding them to the analysis sequence.

What should you do if the R-squared value of the calibration curve is below 0.95?

If the R-squared value is below 0.95, it indicates that the calibration curve is not reliable, and you need to repeat the calibration process to obtain a better curve.

What does the software do after the calibration is successful?

Once the calibration is successful, the software proceeds to analyze the sample, reads the blank solution, standards, and the samples in the specified sequence.

How do you perform the sample analysis after calibration?

You perform the sample analysis by inserting the capillary tube into the sample, starting the analysis sequence, and reading the results after each sample, ensuring proper order and settings.

What is the purpose of the 'Running Man' mode in the analysis?

The 'Running Man' mode is a reading mode that collects data over a specified integration time. It is chosen here to ensure optimal readings during the sample analysis process.

How can the results of the analysis be saved and printed?

The results can be saved as a research file and printed using the software. The printout can be adjusted to the preferred printer settings and includes the analysis data.
