And higher than the metastable helium (He), while the ionization rate and very low (less than 0.5), so Ne ionization efficiency is low, so the response is also low. In order to overcome this difficulty the eye. Changes to improve the electric field gradient enhanced speed of free electrons after ionization to increase the ion flow,<a href="http://www.uggbootsgunstigbillig.com" target="_blank" class="postlink">ugg boots günstig</a>, thereby increasing detection sensitivity, by the author: Choi Hee Chung (1938 a). Women. Senior engineer. In the bow into the analysis instrument, application, development, training,<a href="http://www.stivaliuggboots.com" target="_blank" class="postlink">ugg prezzo</a>, consulting and other work. Had satisfactory results. Certain chromatographic conditions, the detection limit reached Ne 0.1 × 10 a, shown in Figure 1. > Volume flfi: 0.00. , 1.01. , 2.02.53. U3.54. U4.55. Time Imin in Figure IHe U Ne, H. , O. , N. Ne for the detection of low-temperature experiments 1.2Ne security agent, is also an important medium of electric light gas, Ne fill light generated within the perspective of a strong red light, generally used for airport, port lights. Ne demand is increasing. Ne impurity in o, N, CH, Co can be used He gas analysis of the model, which is mainly used in normal operation mode,<a href="http://www.stivaliuggboots.com" target="_blank" class="postlink">ugg italia</a>, Ne, although the main component, but response is not high, do not interfere with o, N, CH, CO, CO. Testing. If you want to measure H / Ne, will need to pre-cut separation of Ne, again separated Ne, H to detect H, then He discharge detector gas chromatograph is also applicable. 1.3Kr, Xe impurity of Kr, Xe content in the air less difficult to extract them in the electric vacuum and electric light has a unique advantage, filling Kr, Xe lamp other than filling a gas lamp energy 2O 3O, luminance 2 ~ 3 times,<a href="http://www.toryburchsaler.net" target="_blank" class="postlink">tory burch shoes</a>, and long life; Kr filled senior tubes, for measuring cosmic rays, Xe lamp light intensity, a little sun is known, in the fog and night navigation, and a special military applications. For Kr, Xe gas is different from the conventional analysis of impurities in the permanent gas detection, it is generally believed that the inert gas group element is not zero reaction to any substance, the actual Kr, Xe and F are halogen compounds. KrF and XeFx compound is unstable and so will form a stable CF, C. F and SF. The presence of these gases, light performance will be affected. Therefore, new detection methods Kr, Xe in the CF, C: F and SF have made detection of the indicator. Used discharge ionization detector gas chromatography to detect CF / Kr, CF / Xe. Kr impurity analysis model used in the cut row (center coral reef flap scorpionfish ∞ ∞ o magic instruments and application of measurement technology juice 4 cut) light component H!, N. O! + CO. CF + CH separated by pre-post-column into the main separation column, and then cut tt} Kr so that discharge from the VENT, cut back on schedule so that the remaining part of the Kr and other impurities in CO, NO, Xe and so once again isolated, see Figure 2.1009896 Name 94 down exhausted 92,908,886 time / min Figure 2Kr detection of impurities in the sample gas Xe retention time in the separation column is longer, but better than zeolite column to advance more. Xe used by the cleaning system of the majority of pre-separation column cleaning discharged. Front component H, N, o + CO, CF + CH,<a href="http://www.toryburchsaler.net" target="_blank" class="postlink">tory burch</a>, Kr, CO. : O, C. F, Xe are well separated. Figure 3. When fffl / rain chart 3Kr, Xe gas mixture of helium impurity analysis 1.4Ar discharge ionization detector for gas chromatography analysis of impurities in argon is also successful. Since room temperature o, Ar retention time in the separation column is similar, Ar in the O is difficult to detect by chromatography on O: the analysis of a specific instrument. Column chromatography using Hayesepdb peak that can make the Ar N, before allowing the detection of a 10 × 10. The N / Ar, smooth detect H, Nz, COz, CH, and detection of the molecular sieve column CO. Figure 4.0246810121416182022 Time / rain in Figure 4Ar N. , CO. Impurity analysis can be easily cut by central implementation, Ar in CO. , H. , N, CH, Co detection shown in Figure 5. 00,51.52.53.54,55.56.57.58.59.5105 time / rain measured in Figure 5 center cutting mode Ar-ion impurities in the discharge of 2 Conclusion detector gas chromatograph coupled with the gas system for rare gases can be analyzed, different requirements can be achieved by special means 10 impurity analysis, DID detector GC gas analysis will be a rare major role.
