Polymetron 9245 钠离子分析仪

Polymetron 9245单通道钠离子分析仪的安装和使用都非常简单，仅需要进行电源和样水的连接。设置是通过控制器进行管理的，该控制器具有清楚的信息，可以指导用户方便地从主菜单进入到子菜单。Polymetron 9245钠离子分析仪的底部配有一个快速循环的阀门，恒定液位器和流速检测允许水样的压力和流速的变化，以及取样点与分析仪之间的距离变化。该仪器的操作原理是离子选择电极法，测量之前首先要调节pH值。水样pH值的调节对于减少温度和其它离子的干扰至关重要。用户可以根据环境温度和水样温度的变化来调节试剂的添加量，保证了pH调节的稳定。当系统中的钠离子浓度持续比较低时，为了保证优佳的响应时间，Polymetron 9245钠离子分析仪集成了电极自动活化装置。自动活化装置使用的是无害的化学品，并能够排除手动活化以及使用危险溶液。

The steamer descended the Woosung River to its intersection with the Yang-tse-kiang, and then began the ascent of the latter. The great stream was so broad that it seemed more like a bay than a river. This condition continued for a hundred and fifty miles, when the bay narrowed to a river, and the far-famed Silver Island came in sight. It stands in mid-stream, a steep hill of rock, about three hundred feet high, crowned with a pagoda, and covered from base to summit with trees and bushes and rich grass. At first it might be taken for an uninhabited spot, but as the boat approaches you can see that there are numerous summer-houses and other habitations peeping out from the verdure. A little beyond the island there is a city which straggles over the hills, and is backed by a range of mountains that make a sharp outline against the sky. This is Chin-kiang, the first stopping-place of the steamer as she proceeds from Shanghai to Han-kow. She was to remain several hours, and our friends embraced the opportunity to take a stroll on shore. Here is Frank's account of the expedition: The unhappy man bowed his head trembling,247 and with dull resignation he left the office, strongly escorted. Three youths, thrilled by the prospect of a mysterious adventure, and a war pilot, intent on a friendly service, discussed plans for protecting the Everdail Emeralds. Captain Parks, however, agreed with Mr. Everdail, who trusted him absolutely—if Sandy did not—that it would be wise not to give any person who had been on the yacht during its crossing any chance to get away. “It’s the hydroplane, then!” Dick decided. “It’s coming from the water-dock inside the boathouse, now—there it is. Hey! You! Stop!” "Well," drawled Cairness again,—he had learned the value of the word in playing the Yankee game of bluff,—"with those about the beef contract and those about the Kirby massacre, also a few I gathered around San Carlos (you may not be aware that I have been about that reservation off and on for ten years), with those facts I could put you in the penitentiary, perhaps, even with an Arizona jury; but at any rate I could get you tarred and feathered or lynched in about a day. Or failing all those, I could shoot you myself.[Pg 260] And a jury would acquit me, you know, if any one were ever to take the trouble to bring it before one, which is doubtful, I think." Then he heard little Abel Waite say: He had anxiously sought the entire length of the camp for something of that kind. He had visited all the sutlers, and canvassed the scanty stocks in the few stores in Chattanooga. He had bought the sole remaining can of tomatoes at a price which would have almost bought the field in which the tomatoes were raised, and he had turned over the remnant lots of herring, cheese, etc., he found at the sutler's, with despair at imagining any sort of way in which they could be worked up to become appetizing and assimilative to Si's stomach. "Johnny...." And years of despair and remorse been your fate, "What ails you, man?" inquired Black Jack—"you look the worse for your long fast—here, drink," handing him a full pitcher. It was in vain that the baroness cast on him a glance that said he had adopted a wrong course—it was in vain that his own better judgment whispered, that he ought to leave the management of the affair in the hands of her who could smile and sooth, when she had an object to attain, without the least violence to her feelings: his anger was set in motion, and it would have required an influence much stronger than the Lady Isabella's to have calmed its ebullition. Although De Boteler spoke so rudely, yet Turner was pleased that it was he whom he had now to contend with; and, looking doggedly at the angry baron, he said, "And if you had never known me," said Holgrave, starting up and grasping Turner's hand, "you need not have changed your name: but you are an honest man, let you be called what you may—and Stephen Holgrave will never forget what you have done for him and his."
