There is an interesting article on NIR News from Pierre Dardenne, where he said: "An RMSC between two standardized instruments measuring the same sealed cup, must be lower than the RMS of the sampling error (obtained by comparing two or several refillings of the same powder". The article is: CALIBRATION TRANSFER IN NEAR INFRARED (NIR News Vol 13 No 4 (2002). Regards J. R. Cuesta |

Hello Nancy, I think that the Standard Error or the Diference between all (SED) should be less than the Sampling Error for that product on the Master. The Sampling error is calculated with the RMS of diferent repacks of the same sample acquired on the Master. Best Regards J. R. Cuesta |

Hello Everyone I hope someone can help me with another question. I have a customer that monitors a network of NIR$ystems 5000 instruments. She maintains the master instrument and standardizes the other 4 to her instrument. After standardization she runs sealed cups on all instruments plus the master. She is asking what type of RMS values are acceptable (meaning a successful standardization) between the spectra from the master and the spectra from a host when scanning the identical sealed sample cup? Thanks in advance for any help you can provide. Nancy |
