R

Root Mean Square noise. A statistical measure of random noise in absorbance readings. Lower RMS noise indicates more stable measurements. Alpha: ≤0.05 mAbs at 700 nm; POP: <0.0002 Abs rms at 700 nm.

Ribonucleic acid. A nucleic acid molecule measured by microvolume spectrophotometers at 260 nm. NanoQ Series supports RNA quantification and purity assessment using the A260/A280 ratio and full-spectrum impurity correction.

A secondary detector that continuously monitors light source intensity and compensates for fluctuations in real time. Used in ProTecUV to ensure high accuracy and long-term measurement stability in inline process applications.

An analytical technique based on inelastic scattering of laser light by molecular vibrations. Provides molecular fingerprint information for qualitative and quantitative analysis. ExPro R Series uses 785 nm Raman spectroscopy for real-time bioreactor metabolite monitoring.
