O

An advanced multivariate statistical method that separates systematic variation correlated with the response variable from non-correlated variation. Used in ExPro R Series and MRX N1 chemometric modeling for improved prediction accuracy.

The distance light travels through a sample. Standard cuvettes use 10 mm pathlength. NanoQ dynamically adjusts pathlength (0.03–1.0 mm) to accommodate a wide range of sample concentrations without dilution.

Open Platform Communications Unified Architecture. An international standard communication protocol enabling interoperability between industrial machines and control systems. ExPro R Series uses OPC UA for seamless integration with bioreactor MES/SCADA/PLC systems for automated fed-batch control.

Optical Density at 600 nm. A standard measurement for estimating bacterial cell density in culture media. Supported by NanoQ Lite+ and Cuve Lite as a dedicated measurement mode.
