UV absorbance measurements of DNA in microplates.
UV absorbance measurements in microplates became possible only five years ago when Molecular Devices (Sunnyvale, CA, USA) introduced the SPECTRAmax 250, the first UV-Visible microplate spectrophotometer. Microplates have since become very popular for making UV measurements of DNA, RNA and protein concentrations because of their higher throughput compared to traditional cuvettes. Despite their ...
متن کاملImpact of Particle Aggregated Microbes on UV Disinfection. II: Proper Absorbance Measurement for UV Fluence
Ultraviolet UV absorbance measurements are subject to significant error using a standard spectrophotometer when particles or aggregates that scatter light are present. True UV absorbance for highly turbid waters should be measured using integrating sphere IS spectrophotometry that allows the collection of reflected and transmitted radiation simultaneously. This is especially important when the ...
متن کاملMiniature Personal Ozone Monitor Based on UV Absorbance.
A new portable instrument has been developed that offers rapid detection of ozone at the ppb level for personal exposure monitoring. The Personal Ozone Monitor is based on the EPA Federal Reference Method of UV absorbance and has the advantage of being small (10 × 7.6 × 3.8 cm), light-weight (0.3 kg), low power (2.9 watts), and battery-operated. The instrument can be worn by an individual durin...
متن کاملData Set 11 : UV Absorbance by Fish Slime
This handout describes the analysis of a repeated-measures experimental design with two crossed among-subjects factors and repeated-measures on a third (withinsubjects) factor. It presents the analysis described in the text: univariate ANOVA with the conservative F test, along with assessment of the validity of the model and with analysis of the effects. A later handout will present linear mixe...
متن کاملRemoval of Azithromycin from aqueous solution using UV- light alone and UV plus Persulfate (UV/Na2S2O8) processes
Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...
