氯化氫检出限值是多少？

返回打印发布时间：2024/1/10 点击：10086

在环境监测和工业生产中，对特定化学物质的测定具有重要意义。其中，氯化氫(HCl)是一种常见的气体，广泛应用于各个领域。然而，了解氯化氫的检出限值是评估其测量准确性的重要依据。

氯化氫的检出限值：

氯化氫的检出限值是指在一定条件下，仪器能够准确检测到的最低浓度。这一数值通常由国家或国际相关标准规定，并以毫克/升(mg/L)或微克/毫升(μg/mL)为单位表示。检出限值的设定考虑到了仪器的灵敏度、操作条件以及可能存在的干扰因素等多个因素。

国内外氯化氫检出限值的相关标准：

1. 中国国家标准(GB/T 7983-2008):该标准规定了气体分析中氯化氫的检出限和重复性，适用于各种气相色谱仪和质谱仪等检测设备。根据该标准，氯化氫的检出限范围为0.5至50mg/L。

2. 美国环保署(EPA):美国EPA发布的关于空气质量监测的标准中，也涉及到氯化氫的检出限值。EPA的标准基于实际应用情况和技术要求，对于不同类型的检测设备和环境条件给出了具体范围。

3. 欧洲标准(EN 1935-2:2013):欧洲委员会发布的关于大气污染物排放监测的标准中，也规定了氯化氫的检出限值。该标准适用于自动站式大气污染物监测设备，检出限范围一般在0.1至10mg/L之间。

了解氯化氫的檢出限值有助于我們評估檢測設備的性能，確保測量結果的准確性。各國相關標准的制定充分考慮了實際應用需求和技術水平，爲我們提供了科學、實用的參考依據。在實際檢測過程中，我們應根據具體情況選擇合適的標准和方法，確保檢測結果的可靠性。

Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off. "Found anything out, mate?" another officer asked. It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid. From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. Sandy’s birthday dawned hot, but clear, with a good, steady south wind blowing. “Jeff calls it a ‘jinx’—a ‘hoodoo’,” responded Dick. “But the chef would discover it—they couldn’t be left there!” She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it." "Neither," drawled Cairness. "But Mrs. Lawton, here, has been good enough to tell me that you have known the exact truth about the Kirby massacre ever since a week after its occurrence, and yet you have shielded the criminals and lied in the papers. Then, too," he went on, "though there is no real proof against you, and you undoubtedly did handle it very well, I know that it was you that set Lawton on to try and bribe for the beef contract. You see your friends are unsafe, Mr. Stone, and I have been around yours and Lawton's ranches enough to have picked up a few damaging facts." The prince found in the Opposition in England the most unfortunate fosterers of his unfilial temper. Pulteney, Wyndham, Chesterfield, Carteret, Cobham, and, worst of all, Bolingbroke, became his associates, and the frequenters of his house. Fast ripening into a pattern of unfilial popularity under such influences, possessing some accomplishments, and a desire to stand well with the people, he married in April, 1736, Augusta of Saxe-Gotha, a princess of so much beauty and good sense, as might have reclaimed many a nature; who seems to have at least won the heart of her husband from his former romantic passion. It was an ominous circumstance, however, that the address of congratulation on this occasion was moved, not by the king's own Ministers, but by the king's own Opposition. Pulteney was the mover, and it was supported by two young men who that evening made their first speeches, and in them burst suddenly forth with that splendour which was destined to grow transcendent through many years. They were Pitt, afterwards Lord Chatham, and Lord Lyttelton. The Deacon had just remembered that he had not seen that individual for some little time, and looked around for him with some concern. It was well that he did. Shorty had come across the haversack that the Deacon had brought, and it awakened all his old predatory instincts, sharpened, if anything, by his feebleness. Without saying a word to any body, he had employed the time while the Surgeon and Deacon were in conversation in preparing one of his customary gorges after a long, hard march. He nearly succeeded. There was silence, in which a coal fell. She still stood with her arms outstretched; he knew that she was calling him—as no woman had ever called him—with all that of herself which was in his heart, part of his own being. "Why, my lord," said Luke, in reply to De Boteler's interrogatory, "there is hardly a free maiden in the parish that would not have been glad of Stephen; but, though I have never seen her, I am told this wife of his is the comeliest damsel between this and Winchcombe: and, besides, she is not like a common nief—and then, my lord, she is the sister of the good monk John."
