The unique chemical and physical properties of carbon nanotubes (CNTs), which make them suitable for a wide range of applications, have stimulated interest for research since their discovery.
Among the developed methods for growing CNTs, the catalytic chemical vapor deposition (CCVD) of hydrocarbon gases turns out to be very promising because of its comparative simplicity, ease of control and low cost. (more…)
Background
The customer supplied us with a special wheel used for chlorine content measurements. The provided sample has nine windows of varying shades of yellow, with a clear center window for reference, as shown in Figure 1. (more…)
A range of options is available for Raman analysis, including systems suitable for handheld, laboratory and educational applications. Systems typically include a spectrometer, laser, operating software and sampling accessories, while modular options are available for users to configure their own Raman systems. Most applications are handled in the 150-3200 cm-1 range, with resolution of ~6-10 cm-1. (more…)

Goal
There was an interest in non-intrusively monitoring pH in tubes containing wet soil samples. This was significant for a number of reasons; this was the first time the reflective patches were to be tested in something other than a cuvette, on a curved surface rather, and this was also the first time an analyte solution was observed that contained sediment or turbidity. (more…)
Abstract
This application note explains how oxygen concentration is measured in the headspace of organic solvents such as Acetonitrile. (more…)
A smart Oxygen Cuvette is developed by coating the inner surface of a cuvette with oxygen sensitive thin film material. The coating is glass like sol-gel based sensor that has an embedded ruthenium compound in the glass film. The fluorescence of the ruthenium is quenched depending on the oxygen level. Ocean Optics phase fluorometer, NeoFox is used to measure this rate of fluorescence quenching and computes it for the amount of oxygen present. (more…)
