The measuring data is required for guaranteeing a precise matrix adaption. For enhancing the data transfer between the laboratory spectrophotometers photoLab® 6100 / 6600 and NitraLyt®Plus, a USB memory stick in combination with the IQ-LabLink function can be used for the MIQ/TC 2020 XT to automatically read the data and store it on NitraLyt®Plus. • Safe, comfortable and fast data transfer • Automatic plausibility check of data 50
