If a number of techniques can be used, the analyst will need to know what the priorities are – is it sensitivity, is speed the most important factor or does expense play a role? This will help in deciding which equipment will best serve the purpose. Finally, experience is also a big factor. If an analyst is very familiar with a piece of equipment and with using it to analyse a variety of samples, it makes a big difference to the confidence in the results obtained. While, if newly trained in a technique, results may be given more tentatively.
G. carbon-13 in the molecule. Sample The sample is placed in the probe which is placed in the centre of the bore. At the top of the probe are coils surrounded by electronics and tuning components. There are also now flow probes, solid state probes and cryogenic (cooled) probes. The cryogenic probes cool the electronics to reduce background noise, which can improve the S/N ratio by 3–4 times. Recently, capillary probes have been reported to give the same sensitivity as cryoprobes but using a lot less sample (active volume only 3 µl)30.
This gives rise to two advantages – multichannel advantage, which improves the signal-to-noise ratio (S/N), and throughput advantage, which allows the use of a single deuterium source for the whole UV–Vis range from 200–780 nm. The greatest recent improvement in spectrophotometers has been in the detector. PMTs are monochannel detectors and are still very popular. They consist of a photosensitive surface and a series of electrodes (dynodes), each at an increased potential compared to the one before.
