ScanDrop® versus Open Drop: Comparison of Reproducibility at Different Wavelengths using K2Cr2O7 and CHIPCUVETTE®
ScanDrop® versus Open Drop: Comparison of Reproducibility at Different Wavelengths using K2Cr2O7 and CHIPCUVETTE®
8 Jul 2015This application note shows the reproducibility of absorption values at different fixed wavelengths through use of an liquid standard, potassium dichromate (K2Cr2O7). The use of ScanDrop® in this application allows for easier handling and a reduction in hands on time and required sample volume. This note also compares the accuracy of the ScanDrop® compared to a market-leading competitor system.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

This will prevent deterioration and cross contamination, and improve the accuracy of sample tracking procedures.UV-Visible-NIRUV-Visible-NIR spectroscopy is used to analyze a wide range of samples based on their absorption of ultraviolet, visible, and near-infrared light. It is commonly applied in chemical analysis, material science, and quality control.
