General analysis of condition, can be cracked O2 Air flow adjustment to 150~500ml/min Within the scope of. ② Ar Airflow: Ar As the carrier gas, the volatile samples carry into the cracked pipe of high temperature parts, oxidative pyrolysis of samples. General requirements for Ar gas flow in the 60~400ml/min range, users can high and low sulfur content of samples, sample size and cracking of o2 gas flow, such as the size of the selection of suitable Ar gas flows. ③ O2 Airborne gas flow: General analysis of liquid samples of relatively light distillate, gas can be without this road. When the samples are less volatile, and Ar gas by adding a certain amount of o2 gas together as the carrier gas, can promote the gasification of the samples. （ 4 ） SY-2000N Program starts As mentioned earlier, run SY-2000N Program, enter the standard sample, sample analysis. 10 Sample analysis: Analysis of liquid samples, for example the following describes the basic operation of samples and some problems should be noticed. 1 ． Sample preparation: Analysis unknown samples by fluorescence analysis of sulfur method, first get the response value of an unknown sample, namely integration area and sulfur content of unknown sample results are based on the same points of reference materials in the condition area, reference materials and sample weight of unknown, unknown score calculated data such as size of the sample. Therefore, prior to the analysis of unknown samples, to pre-select a number of different concentration of standard samples, sample selection should pay attention to the following several points:      （1） With suitable sulfur compounds as solute: （2） With the appropriate solvent, samples, and unknown samples in the sample matrix as close as possible. （3） Use within the warranty period of the standard sample, sample shelf life is one year, so that samples need to be kept. Solutes and solvents are volatile substances the samples should be kept in refrigerated containers, to prolong its service life. 2 ． Sample analysis As mentioned before sample analysis, first select the appropriate sample, sample curve, the concentration of the samples in the standard curve, to ensure sample analysis data is accurate and reliable, if the concentration of the samples in the standard curve in addition to and exceed the minimum sample concentration 10%~20% , Or micro-current amplifier saturation (peak shape for flat peak, need to replace the quantum), asked to reselect the sample making standard curves. 11 Shutdown: Subject to the instrument after use, shut down by doing the following: 1 ． Turn off the UV lamp power supply, cooling by temperature controller button, turn off the furnace power. 2 ． Power down the host, injector, for a few minutes and pneumatic clean after, turn off the gas. 3 ． For two hours, after the temperature dropped off fan switch. 4 ． By balloon tips quit SY-2000N programs into Windows exit window, power off the computer, monitor, printer. 5 ． Distribution box, or power Board total power is off. 12 Reaction chamber-cleaning Because the instrument used for a long time. Reaction indoor residue deposits, resulting in a lower sensitivity, analysis results are not repeated, so users should be based on the use of regular cleaning Chamber. The sediment may be powdered or likely to be oily, its color may be yellow, Brown or black, which mainly depends on the type and operating conditions of the analysis sample, such as material feed speed too high, lack of oxygen, the oven temperature is too low. Cleaning process is as follows: 1 ． Turn off all power switches. 2 ． Open the cover, unplug the darkroom high voltage power and signal plugs, disconnected lines. 3 ． Release the dark base and back panel screws, take out the darkroom later, release the dark end cap fixing screws. (Air road pipelines of end caps). Note: photomultiplier tube-side window shows up, the needs in-side window with a piece of black cloth to block the light. 4 ． Remove Chamber cover screws, carefully removing the gland, filters, Quartz. If the "o"-ring broken, replace it with new. 5 ． Cleaned the mirrors of wadded paper with high silica film and filters, wipe with clean soft cloth with no hair reaction indoor wall, if necessary, get scrubbed clean with acetone or ethanol, and oxygen blow dry. 6 ． Reaction chamber-cleaning is complete, again in order to install. Note: when fixed optical filters, quartz, and action should be smooth, degree of tightening to ensure airtight, beware of filters, quartz plate rupture. Filters, quartz plate location do not install anti-, quartz reaction indoor wall that protects the filter. 7 ． Fixed to the Chamber after Chamber, anechoic chamber attached to the detector, and connect all cables and gas pipelines to avoid leaks, leakage phenomenon. 8 ． Cover the cover. 13 Instrument maintenance 1 ． Long-term use of the system, pneumatic joints leakage may occur, users response to the gas as a whole do not regularly checked. 2 ． Users should always check after cracking tube outlet port and with and without the carbon in the gas circuit. If cracking tubes of carbon deposition in, you can access oxygen combustion in high temperature conditions clear. If carbon deposits in the pipeline. The timely replacement of new line. 3 ． Users should be required to replace the oxygen desiccant, to ensure that the system is functioning properly. Note:1. Air drier stuffing (5A molecular sieve ) Processing method : 500 Temperatures, activation of 4 Hours. 4 ． Check the use of cracked pipes on a regular basis, if the cracked pipe wall becomes white and rough, instructions for quartz tube lifetime had to, it should be replaced immediately. Analysis of low concentration samples usually, demanding to the Lysis tube, cracked pipe inner wall roughness can lead to drop in its signal strength decreases, lower sensitivity, resolution, Lysis tube on low concentration sample analysis does not apply may also apply to the analysis of high content of samples. 5 ． Periodic cleaning Chamber, cleaning methods, see the fifth chapter. 6 ． Injector regularly driven screw Guide bar and add lubricant to reduce wear and noise.
