N

Measurement of DNA and RNA concentration using absorbance at 260 nm. A primary application of NanoQ Series microvolume spectrophotometers, supporting dsDNA, ssDNA, RNA, and miRNA measurements.

Root Mean Square noise. A measure of random signal fluctuations in absorbance readings. Alpha achieves ≤0.05 mAbs RMS at 700 nm and ≤0.4 mAbs RMS at 240 nm, ensuring highly stable measurements.

Reference materials or calibration standards that are traceable to the National Institute of Standards and Technology. K LAB validates photometric accuracy using NIST SRM 930d/1930 (neutral density filters) and SRM 935a (potassium dichromate).

Spectroscopic technique using electromagnetic radiation in the 900–2500 nm range. NIR absorption corresponds to overtone and combination bands of molecular vibrations. Used by MRX N1 for non-destructive, high-throughput quantitative analysis.
