The following is for C and/or N analyses of solid samples. If you know the amount of carbon and nitrogen in the sample (by percent) and will be weighing your own samples, you may use the sample weight calculator given just below. If using the calculator, it would be helpful to let us know the values you used for the percent carbon and nitrogen once you submit your samples. Feel free to contact UASIL if there are no sample weights listed by the calculator.

Enter the percent carbon of the sample: %
Enter the percent nitrogen of the sample: %
