英國(guó)Sherwood氯化物分析儀926/926S
產(chǎn)品特點(diǎn)：
1.英國(guó) Sherwood 926/926S型氯化物分析儀，主要用于氯離子的檢測(cè)，它是通過氯離子跟硝酸銀形成氯化銀沉淀不容物質(zhì)來(lái)檢測(cè)氯離子
2.緩沖系統(tǒng)：專為設(shè)計(jì)出去干擾離子，并和一種特殊分散劑結(jié)合，能將沉淀再現(xiàn)，使得信息重復(fù)性好，從而提高了分析的準(zhǔn)確性
3.人體功率學(xué)設(shè)計(jì)的微處理器，操作方便，維護(hù)簡(jiǎn)單為926型設(shè)計(jì)的緩沖系統(tǒng)突出提高了靈敏度和選擇性
4.應(yīng)用領(lǐng)域：
食品工業(yè)和乳品加工工業(yè)中的氯化鈉濃度的測(cè)量
工業(yè)加工中的污染檢測(cè)（能檢測(cè)出沸水中ppm級(jí)含量的鹽分）
土壤，泥漿的分析（用于脫鹽作用的研究和土壤質(zhì)量分析）
臨床的應(yīng)用（血液，體液中的鹽分平衡，遺傳性胰腺病的診斷，能檢測(cè)20微升的樣品）
其它行業(yè)，制藥，水泥，粘合劑的制造等等

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.
