A

A feature of NanoQ that automatically selects the optimal optical path length (0.03–1.0 mm) based on sample concentration, ensuring accurate measurements across a wide dynamic range without manual adjustment.

A chronological record of user activities within a software system, including login, measurement, data handling, and reporting. Required for FDA 21 CFR Part 11 compliance. Supported by K LAB’s Secure software.

American Spice Trade Association color measurement standard used to quantify the color intensity of red spices such as red pepper powder. Measured using UV-Vis spectrophotometry at specific wavelengths.

A family of RISC-based processors used in embedded systems. NanoQ uses an Octa Core ARM® Cortex™-A53 processor, and POP uses an ARM Cortex-A55 processor to enable stable stand-alone operation.

Analog Input/Output interface used for signal communication between instruments and external control systems. ProTecUV supports 0–20 mA or 4–20 mA analog I/O for PLC connection.

The degree of repeatability in absorbance measurements under identical conditions. Expressed as standard deviation or %CV of repeated measurements.

The closeness of a measured absorbance value to the true or reference value. Typically validated using NIST-traceable reference materials such as potassium dichromate (SRM 935a) or neutral density filters (SRM 930).

A measure of the quantity of light absorbed by a sample at a given wavelength. Expressed in Absorbance Units (AU). Calculated as A = log(I₀/I), where I₀ is incident light intensity and I is transmitted light intensity.
