英国Sherwood氯化物分析仪926/926S

产品特点：

1.英国 Sherwood 926/926S型氯化物分析仪，主要用于氯离子的检测，它是通过氯离子跟硝酸银形成氯化银沉淀不容物质来检测氯离子

2.缓冲系统：专为设计出去干扰离子，并和一种特殊分散剂结合，能将沉淀再现，使得信息重复性好，从而提高了分析的准确性

3.人体功率学设计的微处理器，操作方便，维护简单为926型设计的缓冲系统突出提高了灵敏度和选择性

4.应用领域：

食品工业和乳品加工工业中的氯化钠浓度的测量

工业加工中的污染检测（能检测出沸水中ppm级含量的盐分）

土壤，泥浆的分析（用于脱盐作用的研究和土壤质量分析）

临床的应用（血液，体液中的盐分平衡，遗传性胰腺病的诊断，能检测20微升的样品）

其它行业，制药，水泥，粘合剂的制造等等

1.More accurate and precise than any other rapid method of salt determination

2.Measurement repeatability ensures quality assurance and control

3.Compact design saves valuable bench space

4.Chloride standards are calibrated in both mg/L and mmol/L

5.This automatic chloride titrator provides accurate and highly reproducible measurement results. The system is ideal for use in the food， pharmaceutical， agricultural， and petroleum industries.

6.The system utilizes a method based on coulometric titration an absolute method where the reagent， silver ions， is precisely and quantitatively generated at the time of analysis by passing a constant current between electrodes.

7.The end point is detected by the use of sensing electrodes which measure the change in the solution conductivity that occurs when excess silver ions are present in the solution. Unlike a conductivity meter， this analyzer actually titrates chloride with silver as in official methods.

8.Automatic features provide speed and simplicity， reducing labor costs and improving results. Titrations are performed in less than 72 seconds and results are digitally displayed in % salt or mg/L chloride. The sensitivity of this system enables measurements in the ppm range for boiler feed water， polymer washes， bore-hole slurries， as well as soil salinity studies.

9.The acid buffer reagent is a nonhazardous mixture of glacial acetic and nitric acids， together with other components designed to give highly reproducible results.

10.The reagent provides the strong acidic medium required for the dissolution and reaction between the silver and chloride ions. Silver cleaning polish is provided to keep the pure silver electrodes in good condition.

11.Use this system as a stand alone chloride and salt tester or take advantage of the RS232 PC connection to integrate data into your spreadsheets， databases， or LIMS software.

12.What’s included: printer cable， RS232 port， acid buffer reagent (500 mL)， 200 mg/L chloride standard (100 mL)， one set of electrodes， three anodes， two 14mL marked beakers， electrode cleaning polish， stirrer， and 6-ft power cord with U.S. plug.
