Most microvolume spectrophotometers rely on surface tension to bridge an air gap when measuring samples. Erroneous results will occur if the sample surfaces are not bridged. This note describes how the DS-11 Series eliminates these concerns using SmartPath™ technology with Bridge Testing™ verification.

The DeNovix DS-11 Series Peptide app enables protein or peptide concentration determinations based upon absorbance values at either 215 nm or 205 nm. Data is presented for polymyxin B demonstrating the DS-11 can be used to determine the concentration of peptides over a wide dynamic range.

This document presents typical performance data comparing dsDNA measurements made using a DS-11+ versus measurements made using an Agilent 8453 Spectrophotometer across a concentration range measurable using a 1 cm cuvette.

The DeNovix DS-Series Spectrophotometer / Fluorometer software includes an intuitive Data app, which enables the user to recall and export data at their convenience. This document will highlight some of the key features of the app.

The DeNovix DS-11 Series propriety SmartPath™ technology enables accurate pathlength control and eliminates the need for routine recalibration, labs may choose to run the Diagnostics app to verify that the instrument is working within specifications

Purity ratios are routinely used to identify contamination in samples when quantifying using UV-Vis. Understanding their utility and threshold values is essential to correct interpretation.
