D

The range of concentrations or absorbance values that an instrument can accurately measure. NanoQ achieves a wide dynamic range (2–27,500 ng/μL for dsDNA) through its 4-point auto pathlength system.

Double-stranded DNA. A common nucleic acid measured by microvolume spectrophotometers. NanoQ can detect dsDNA in the range of 2–27,500 ng/μL using the 260 nm absorbance peak.

A spectrophotometer that splits the light beam into two paths — one through the sample and one through the reference — simultaneously. This compensates for light source fluctuations, providing higher accuracy and stability than single-beam systems. Used in Alpha.

A UV light source emitting radiation in the 160–400 nm range. Used in combination with a tungsten halogen lamp in Alpha and POP to cover the full UV-Vis spectrum. Automatic lamp switching occurs at 340–410 nm.
