DETAILED DESCRIPTION AND SCOPE:
Argon gas is needed to clean the Optics Chamber in which is an increased optical element like the Grating and the detectors, and also to clean the Spark Chamber. We can obtain Good overall savings in the consumption of Argon gas; it is significant to effect savings in all the above-mentioned Argon Flow Conditions. It's started with CCDs; PMTs CCD is a type of image sensor that detects light. . The light-sensitive capacitors detect the intensity of light received and convert it into an electrical signal. Each pixel on the CCD represents a specific wavelength of light, and the more photons absorbed, the more electrical signal generated. Each pixel on the CCD represents a specific wavelength of light, and the more photons absorbed, the more electrical signal generated and highly accurate they have much better long-term stability too. Spectrometer manufacturers use Argon Flow/Purge in the following ways (A) while sparking (analyzing) Argon is made to flow through the Spark Chamber at 3 - 5 LPM. (B) When not sparking, in standby mode, Argon is purged through the Spark Chamber at 0.50 LPM. (C)Argon is also purged through the OC @ 0.50 LPM. In order to obtain good overall savings in the consumption of Argon gas, it is important to effect savings in all the above- mentioned Argon Flow Conditions. Argon gas is purged through the Spark Chamber at regular intervals.
The Spark Chamber is also designed as small as possible and is kept closed during periods of non-use using a plate with a gasket for proper sealing. All operations are automatic using software and timings are optimized.
Method for Argon saving in the Optics Chamber:
The optical chamber has consequently been constructed with two solenoid valves - one for "Argon In", the other for "Argon Out". Argon purging is started in the Optics Chamber at 0.50 LPM. After an optimized prearranged gap, the Argon Outlet Valve is shut. The Argon Inlet Valve is then shut after a short gap of the Outlet Valve shutting. This ensures trapping Argon in the Optics Chamber at a little higher pressure than atmospheric pressure. To ensure that conditions inside the Optics Chamber (pressure and consequently the refractive index of the medium inside the Optics Chamber) are precisely the same during each spark, purging through the Optics Chamber is started concomitantly with each spark.
Method for Argon saving in the Spark Chamber:
If samples are being analyzed at standard gaps, even if purging through the Spark Chamber is stopped for petite periods, analysis is not adversely affected. During longer periods of non-analysis, to keep the spectrometer in good quality running situation, Argon gas is purged through the Spark Chamber at regular intervals. The Spark Chamber is also designed as small as possible and is kept closed during periods of non-use using a plate with a gasket for appropriate sealing.

A highly developed atomic emission spectrometers as claimed as claim 1 wherein Argon is purged through Spark Chamber because without Argon amputation, exterior air would come into the Spark Chamber. Air holds besides other gases, Oxygen & water vapour. Both are injurious for good sparking. Also, Oxygen would suck up all wavelengths below 200nm.
14. A highly developed atomic emission spectrometers as claimed as claim 1 wherein It is kept closed for the duration of periods of non-use using a plate with a gasket for appropriate sealing.
15. A highly developed atomic emission spectrometers as claimed as claim 1 wherein All process are automatic using software and timings are optimized
16. A highly developed atomic emission spectrometers as claimed as claim 1 wherein The Optics Chamber has therefore been constructed with two solenoid valves - one for "Argon In", the other for "Argon Out".
17. A highly developed atomic emission spectrometers as claimed as claim 1 wherein Argon purging is started in the Optics Chamber at 0.50 LPM.
18. A highly developed atomic emission spectrometers as claimed as claim 1 wherein an optimized prearranged gaps, the Argon passage Valve is shut.
19. A highly developed atomic emission spectrometers as claimed as claim 1 wherein The Argon Inlet Valve is then shut after a short interval of the passage Valve shutting.
20. A highly developed atomic emission spectrometers as claimed as claim 1 wherein this ensures trapping Argon in the Optics Chamber at a slightly higher pressure than atmospheric pressure.
21. A highly developed atomic emission spectrometers as claimed as claim 1 wherein To ensure that conditions inside the Optics Chamber (pressure and consequently the refractive index of the medium inside the Optics Chamber) are exactly the same during each spark, purging through the Optics Chamber is started concomitantly with each spark.
22. A highly developed atomic emission spectrometers as claimed as claim 1 wherein If samples are being analyzed at regular interval s, even if purging through the Spark Chamber is stopped for short durations, analysis is not adversely affected.
23. A highly developed atomic emission spectrometers as claimed as claim 1 wherein During longer periods of non-analysis, to keep the spectrometer in good running condition, Argon gas is purged through the Spark Chamber at regular intervals.
24. A highly developed atomic emission spectrometers as claimed as claim 1 wherein Argon gas is purged through the Spark Chamber at regular intervals.
25. A highly developed atomic emission spectrometers as claimed as claim 1 wherein The Spark Chamber is also designed as small as possible.
26. A highly developed atomic emission spectrometers as claimed as claim 1 wherein it is kept closed during periods of non-use using a plate with a gasket for proper sealing.
