In conventional UV/Visible spectrophotometers, the sample is usually contained within a glass or silica cuvette which is placed in the sample beam. The absorbance of this is measured and then compared to that of a standard. From this comparison, the concentration is calculated.
However, when the quantity of sample is limited or highly concentrated, dilution - or the use of ultra low volume cuvettes is required, which is time consuming, can introduce errors and presents cleaning difficulties.
NanoVue was developed to overcome these problems. Using NanoVue, typical sample volumes of 2µl are pipetted onto a hydrophobic surface and then a very short pathlength of either 0.2mm or 0.5mm is created by lowering the sampling head onto the top of the sample.
With the sample so constrained, all of the general software features of the instrument, includ
