實驗室鈉參比電極(5102S-MCX-0.6m型)使用維護知識

发表时间：2018-04-04 11:45

使用前注意事項
? ?1、請在使用前仔細檢查外觀，看看是否有破損或裂紋，如有則及時與廠家聯系更換；
? ?2、電極前端的保護帽內有原廠提供的實驗室參比電極填充液，電極浸泡其中以保持電極的活化狀態。測量時取下保護帽及電極上端小孔處的橡膠帽，用蒸餾水沖洗幹淨電極；
? ?3、將電極接至測量儀的參比輸入口；
? ?4、測量前應使用被測溶液反複沖洗電極和容器，一般測量高濃度溶液時，至少用待測溶液沖洗2次，測量低濃度溶液（pNa6以下）時至少用待測溶液沖洗3次
? ?5、測量後，請將電極放回保護帽中，並將橡膠帽套回電極小孔處，以保證下次正常使用，切忌將電極長時間（不超過6小時）放置于純水中。

保管與維護
? ?1、電極如較長一段時間（一般超過1个月）不使用，则应将其用蒸馏水冲洗干净，放入装有实验室参比电极填充液的保护帽中存放；
? ?2、電極使用時，電極上端小孔的橡膠帽應拔去，以增加液體壓力，加快電極響應速度。當液面低于加液孔下75px時應及時補充新的實驗室參比電極填充液；
? ?3、使用操作時切忌用手指觸摸電極杆，以免影響電極測量結果及壽命；
? ?4、電極插口必須保持高度的清潔和幹燥，防止被溶液腐蝕。
? ?5、爲不影響參比電極性能，注意新購買的實驗室參比電極填充液使用前，必須先清除幹淨原參比電極剩余填充液，然後再加入少量新的參比填充液沖洗一次，**再加入新的參比填充液至加液孔位置即可。

用途
? ?5102S-MCX-0.6m參比電極必須與我公司生産的測量電極配合使用，用以測試水溶液中鈉離子的含量。

DANGEROUS PLACE ON THE SUWO NADA. DANGEROUS PLACE ON THE SUWO NADA. "Richard, it helps the wrong way; I know that story. After hearing that story she is, yes! the one woman of all women to send me this." Another day arose. A courier brought passes for our three or four other wounded to go home as soon as they were fit to travel, and by night they were all gone. At early bedtime came two surgeons of high rank all the way from Johnston's army up in Mississippi. General Austin had asked this favor by telegraph. Harry had been gone thirty-six hours, and Ferry was just asking if he had not yet got back, when the surgeons came in to the room. A pleasantry or two consumed a few moments. Then the surgeon in charge of us told of a symptom or two, to which they responded only "hmm," and began the examination. Miss Harper sent her three nieces away. I lay and listened in the busy stillness. Presently one of the examiners murmured with a certain positiveness to the other, who after a moment's silence replied with conviction; Miss Harper touched our surgeon's arm inquiringly and he looked back in a glad way and nodded. Miss Harper nodded to me; they had located the ball! Now the conversation turned upon men and events of the day, while one of the visitors, with his back to the patient, opened a case of glittering knives. Presently the professional heads came so close together as quite to hide the patient; they spoke once or twice in a manly soothing tone. Miss Harper stroked my temples to keep me down, one of the busy ones spoke again, and lo! the thing was done, there was the ball in the basin. As the men of blood sped through their kind after-work the news flew to and fro; Camille wept,--since she could not hurrah,--Cécile told Charlotte, the heavenly-minded Estelle was confirmed in her faith, Miss Harper's black eyes, after a brief overflow, were keener and kindlier than ever, and as the surgeons spoke the word "done," Ferry asked again if Harry had not got back yet. Pretty soon Harry did arrive, with news of great feats by our cavalry against our old enemy Grierson, in which Austin's brigade had covered themselves with glory, and in which he had had his own share; his hand was swelled as big as his heart. In all the Confederacy no houseful went to sleep that night in sweeter content. I sank into perfect bliss planning a double wedding. "Well, I can name several! I don't call Scott Gholson anybody, but there's Major Harper--No, I'm not talking too loud, Ned isn't hearing a word. Major Harper's so hot against this thing that he brought it up, with me, yesterday on the battlefield." Mrs. Flack held the greater part of herself in a semicircle of red arm. "You are a one," she declared. Then she looked at Mr. Flack, who sat unmoved. "Why don't you laugh. It would do you good. You take everything so serious." "Certainly, captain." The final defeat of polytheism proved, in some respects, an advantage to Neo-Platonism, by compelling it to exchange theological controversy for studies which could be prosecuted, at least for a time, without giving umbrage to the dominant religion. At Alexandria the new spiritualism was associated, on genuinely Platonic principles, with the teaching of geometry by the noble and ill-fated Hypatia. In all the Neo-Platonic schools, whether at Rome, at Alexandria, at Constantinople, or at Athens, the writings of Plato and Aristotle were attentively studied, and made the subject of numerous commentaries, many of which are still extant. This return to the two great masters of idealism was, as we have already said, the most valuable result of the metaphysical revival, and probably contributed more than any other cause to the preservation of their works amidst the general wreck of ancient philosophical literature. Finally, efforts were made to present the doctrine of Plotinus under a more popular or a more scientific form, and to develope it into systematic completeness. [Pg 50] Beyond the "deadening" came a horde of pursuing rebels, firing and yelling like demons. The sight and sound swelled the boys' hearts with the rage of battle. "Why, what in the world have I got on that's military?" asked Billings, looking himself over. "Stephen, you were not used to answer me thus. I charge you, by the authority and love of thy mother, and in the name of the blessed saints, to tell me what has happened." HoME 飞鹰伦理影院ENTER NUMBET 004www.ooqm.com.cn
