Understanding How True Path Technology™ Allows Accurate Measurement of Ultra-Low Volume Samples

The True Path Technology™ of the NanoPhotometer^® NP80/N60/N50 allows the instrument to provide accurate and reliable measurements for ultra-low volume samples of 0.3 µl to 2 µl. This technical note explains how the True Path Technology™ uses two accurate path lengths as fixed anchor points, in order to create a calibrated optical environment that does not change over time. This provides accurate and linear results over the lifetime of the instrument without any need for recalibration.
