In the first step, you should open the Excel workbook that contains the known values that you want to plot on the calibration curve. In our example, the x- values will represent the standards, while the y-values will be our responses.Īfter getting the calibration curve, we'll use the SLOPE and INTERCEPT functions to calculate the formula of the calibration curve. The data pairs will represent x-values and y-values.

To demonstrate how to create a calibration curve in Microsoft Excel, we'll develop ten data pairs that we'll use as examples. What steps should you follow to ensure you create a calibration curve? You need to follow a few steps to ensure you end up with the proper calibration curve. How Do I Create a Calibration Curve in Excel?Ĭoming up with a calibration curve in excel is a straightforward process. You can then use the linear calibration curve to predict the concentration of a sample of the solution by relating its instrument response to the concentration of the standard solution. Then, you measure the instrument response for each sample and then compare it to the concentration of the standard solution. You create a calibration target curve by first preparing some standard solutions with known concentrations of the analyte sample. Additionally, you can use a linear calibration curve to help you to predict the concentration in a sample of a solution. When you enter the values into simple formulas, you will calculate the true value using any measurement.Ī calibration curve is essential in understanding calibration data and getting insights into the instrumental response to an analyte. Alternatively, you can calculate the equation of the line using the SLOPE and INTERCEPT function in Microsoft excel. Plotting the data pairs in the chart is essential for data display. Microsoft Excel comes with features that help you plot the data pairs in a chart, add a calibration curve (trendline), and display the curveé equation on the chart. Thus, the line helps you to fill the information between the two known points to be certain when you want to estimate the actual temperature when the thermometer is reading 57.2 degrees, but you haven't measured the standard that corresponds to the reading. If the thermometer has a linear response, you can pick any point on the line that will correspond with the value of the thermometer display, and you'll get the corresponding true temperature. You can plot the two data pairs and draw a calibration curve between them. The first pair will be when you put it in ice water (320F or 00C) and put it in boiling water (2120F or 1000C). If you calibrate a thermometer using the freezing and boiling points of water, you'll end up with two data pairs. The comparison helps you come up with data pairs that you can use to come up with a calibration curve. Examples of standards include the boiling points and freezing points of water. What Is a Linear Curve and How Is Excel Useful When Creating One?ĭuring calibration, you compare the readings of a device, such as the readings that a thermometer displays, and compare them with known values, referred to as standards. Additionally, we'll look at how to use the SLOPE and INTERCEPT functions to do the calibration equation in Microsoft excel. Here, we'll look at how you can use Microsoft Excel to create a chart, how to plot a linear calibration curve, and how you can display the liner curve formula. Microsoft Excel features charting tools that offer an excellent way of plotting the known relationships of ordered and unordered pairs.
