For quartz, a little extra budget is needed, but you also get a larger transmission range of 190 to 2,500 nm. If the wavelengths in the UV range, below about 300 nm, quartz cells or a special type of plastic are to be used, which provide sufficient transparency in this range. Polystyrene buckets are the least expensive, but they have the lowest chemical resistance and are only suitable for applications in visible light, with a lower wavelength limit of about 340 nm. Methyl polymeth acrylate (PMMA or “acrylic”) buckets extend that range to about 300 nm, or something in the nearBY UV range, and have slightly higher chemical compatibility. The brand’s UV buckets use a patented plastic to allow measurements up to 230 nm and have resistance to many polar organic compounds, as well as many acids and bases.
Here we demonstrate a one-step UV-vis spectroscopic analysis without dilution of high concentrations of platinum hexachloride in a micropilar matrix, i.e. “pillar bucket”. The bucket is spontaneously filled by absorbing the liquid sample into the micropilar matrix. The height of the pillar determines the length of the optical path, which was reduced to between 10 and 20 μm in this study. Only one small drop (∼ 2 μL) sample is required and the volume delivered does not have to be accurate or even known to the analyst for accurate spectroscopy measurements.
Uv vis cuvette for spectrophotometry is transparent for the wavelength of light in the UV fish ranges for measurements. As a result, the bucket itself does not cause problems during the examination. The solution should be placed in the light path uv vis cuvettes of the UV/fish spectrophotometer. A micropipette is used to inject the sample directly into the bucket and the bucket is ready for use. A well-known application of the short-path length bucket is infrared range spectrophotometry measurement.
And the NRC will not work with organic solvents, instead it should go with CRF or HTR versions. The wavelengths of the bucket to be used are determined by the material of the bucket. Sufficient transmission is important for the bucket so that dimming light to the transparent walls of the cell does not have a negative effect on the measurement result.
If wavelengths are used in the UV range, below about 300 nm, buckets of quartz glass or a special type of plastic should be used, which provide sufficient transparency in this range. The polystyrene trays are designed for testing over the entire visible spectral range from 340nm to 750nm. A standard light path of 1 cm and recessed windows provide light transmission. You can reduce your test volumes to save on expensive reagents. They require only a filling volume of 1.2 ml in the size of 1.5 ml. Although plastic buckets can only be reused a few times, they are cost-effective.
