Another widely used highly pure material is aluminum oxide. Crystals and 
sapphire crystals are grown from highly pure alumina. Sapphire in its performance 
is considered the second most durable element after diamond. 
Hardware components of the peak start and end detection device are based 
on ADC of tracking type. It consists of a four bit shift register and a logic element 
"4 AND" at the output of which a signal will appear corresponding to the 
beginning and end of the peak. 
Fig.1. Schematic diagram of “peak start and peak end” detection devices 
based on ADC of tracking type 
As can be seen from the above, the peak start and peak end detection devices 
based on ADC of tracking type are much simpler and cheaper than similar devices 
based on other types of ADC converters. It should be noted that the ADC and the 
peak start and end detection device are connected to each adsorption column 
individually. As a result, ten thousand pieces of ADC and peak start and end 
detection devices should be used in the construction of the deep purification 
system. 
Summarizing the above mentioned, one can note that with the tracking type 
ADC it is possible to obtain substantial cost saving in the course of designing and 
operating of a deep purification system. 
When constructing a high-degree purification system, the number of 
amplifiers, ADCs and peak start and end detection devices should correspond to 
the number of adsorption columns. Given that the high-degree purification system 
has a large number of adsorption columns, even a slight cost reduction of the data 
processing system at the output of the adsorption column will lead to significant 
cost savings in general.
