1.1 This practice is for the determination of the heating value measurement of gaseous fuels using a calorimeter. Heating value determination of sample gasses containing water vapor will require vapor phase moisture measurements of the pre-combustion sample gas as well as the non-condensed gasses exiting the calorimeter. Instruments equipped with appropriate conditioners and algorithms may provide heating value results on a net or gross and dry or wet basis. 1.2 This practice is applicable to at-line and in-line instruments that are operated from time to time on a continuous basis. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
对于部分城市天然气管道的区域性限制,无法将天然气通过束管直接对接上天然气(热值)分析气相色谱仪十通阀进样口,这就给使用取样袋采样带来一定的挑战,为达到准确分析的目的,需减少取样时的外来空气干扰,具体有以下几个注意事项: 1、尽量使用标准的不锈钢取样器或聚四氟球胆气袋进行采样,zui大限度的减少污染。 ...
我公司依据GB/T13610-2014《天然气的组成分析气相色谱法》、GB/T12206-2006《城市燃气热值和相对密度测定方法》、GB/T11062-1998《天然气发热量、密度、平均密度和沃泊指数的计算方法》检测分析要求,采用GC-9860气相色谱仪配置热值工作站,一次进样双柱并联同时分析部分微量永久气体及C1-C8组分和热值,并通过加装FPD检测器又可检测分析城市管道天然气中硫化物--加臭剂四氢噻吩...

比色法甜蜜素仅有微弱的紫外吸收,故不宜直接用紫外检测,需要进行衍生反应后,才能进行紫外测定。常用的衍生方法是重氮化和氯化。比色法是国标中第二法,利用甜蜜素在硫酸介质中与亚硝酸反应,生成环己醇亚硝酸酯,与磺胺重氮化后再与盐酸萘乙二胺偶合生成红色染料,在550nm波长测定其吸光度。3. 薄层色谱法薄层色谱法是国标中第三法。...
