Subsequent Certification Samples
Certification Check Samples - Entering Sample Numbers
Your system was set up by Caltest, at the time of it’s software’s installation, to collect NIR spectra and NIR results By Product. When you run a sample, the NIR spectrum of that sample, and the analysis results of that sample, will be stored, automatically, into a file having the same name as the calibration equation selected for the analysis, but with extensions .NIR and .DAT, respectively. Caltest did not alter the storage selection of your .ANL file which is also used to collect your analysis results. You can continue to use the .ANL as you have always done before without adversely affecting the Caltest Certification Program.
Example:
You have just run a sample of Poultry Feed on your NIR system.
You then select the calibration you want to use to predict the results from the product list in the ISI software.
When you pick Poultry Feeds from the list, you will notice that at the bottom of your computer screen is the actual name of the calibration equation you selected:
PFDUOFE.EQA
When you complete the process of obtaining your results on your computer screen and you move on to the analysis of your next sample, your computer will automatically store the spectra in the file:
PFDUOFE.NIR
and the results in the file:
PFDUOFE.DAT
Caltest needs to find the Certification Check Samples you run, on your NIR, within the .NIR and .DAT file that is updated by your computer each time you run a sample.
When you run a sample, one of the prompts you will get, will be a purple colored box(1) requesting that you input some form of a sample number. This box can accommodate up to 12 alpha-numeric characters. If you usually type in a number, or some other sample identifier, into this box, Caltest requests that you now start using a sample number with only a maximum of eight characters for your routine analyses. You should leave at least four positions at the end of your sample number to accommodate the assignment of a random number when you run the Certification Check Sample or encounter a Global H outlier.
Example:
You normally allow your system to automatically increment sample numbers for you each time you run a sample. Your purple box(1) might look like this:
375
If the number 375 happens to be in the purple box(1) at the time you intend to run your Certification Check Sample, you can leave the 375 in the box but add, after the 5, a dash (-) followed by the three digit random number you selected from the 10-Week, 10-Month or ‘H’ Outlier pages in the "Notes & Information" section of your documentation.
Assume that the Certification Check Sample that has been selected by you after using the tables in the "Notes & Information" section of your documentation has the Random Number 065, the purple box1 should look like this: 375-065
If you do not normally enter a sample number, or do not allow your system to automatically increment sample numbers for you each time you run a sample, then the purple box(1) should look like this: 065
If you allow your system to automatically increment the date and time as your sample numbers, you will need to backspace at least the time shown in the purple box(1) so as to accommodate the four character random number of your Certification Check Sample or Global H outlier.
131298-065
The random number pair you select for your split Certification Check Sample or Global H outlier will be the next pair of random numbers that have zeros in the NIR and Lab columns, and immediately follow a random number pair that have NIR and Lab values.
(1) Windows versions of the ISI software (WINSCAN and WINISI) may not display purple colored boxes as the areas designated for entry of sample numbers. Apply this same procedure for the designated sample entry areas of the Windows versions of ISI software.
