The platinum apparatus is indispensable for Modern chemical analysis. Platinum has greater applicability in the field of scientific experiment and chemical reactions. There are certain ranges of products which are particularly created for XRF laboratory for the use of X-ray fluorescence.
Predominantly in X-ray fluorescence analysis (XRF), all the samples have to be dissolved in a molten oxide flux, for example in lithium tetraborate glass melt. Here the process of fusion is normally carried out in a platinum-made crucible due to its corrosion by the flux and resistance to oxidation. However, then the melt is cast to a platinum dish and it will attain the same flatness and smoothness. Thus in this process, the platinum apparatus offers an ideal environment to conduct the analysis.
Platinum is a metal which is basically inert, and sue to that reason it does not get contaminate with another chemical while it is at the process of a normal sample. It is highly resistant to heat analytical purposes. Even after a prolonged period of exposure to the high temperature of above 1000°C in the air also the Platinum crucibles shows no significant weight loss in their behavior.
But there are certain basic precautions and tips are there which should be observed in laboratory exercise in order to get the maximum utility of using platinum. The main objective here is to aware the user about the histories resulting from inadequate caution followed in practice.
Often if proper prevention at an appropriate time is not being taken then a risk of getting the poison of the metal has been observed. Sometimes it may generate quite a harmful element.
Those bad effects are generally termed as “platinum corrosion”. This corrosion is however in general sense refers to aqueous corrosion or rusting, etc. While platinum gets with the contact of other metal it is found with some chemical reaction of platinum with another element due to the lower melting point of the metal. The best example of the situation is that while platinum gets contact with arsenic the compound then forms a eutectic mixture.
Apart from arsenic, the other examples of poisons that can be created with the contact platinum are boron, phosphorus, bismuth, sulfur, silicon along with several heavy metals, such as lead, tin, zinc, antimony, etc. Furthermore, carbon can cause structural disintegration of platinum at elevated temperatures. Moreover, platinum can be caused by structural disintegration through carbon at high temperatures.
