Pour-Thru cell methods for DR/2400 DR/2500
 
问：是否用Pour-Thru cell 流通池配合DR/2400 or DR/2500 分光光度计使用可以测量任何参数?
 
答：不是的。但Most parameters can be tested using the 1-inch Pour-Thru Cell, however there are some important exceptions. The Pour-Thru Cell cannot be used to measure the following parameters:

          oAluminum (ECR method), Arsenic
          oBarium, Boron (Carmine method)
          oCyanuric Acid
          oFluoride, Formaldehyde
          oLead (LeadTrak method)
          oMercury
          oNickel (Heptoxime method), HR Nitrite
          oPCB, Phenols, Potassium
          oSelenium, Silver, Suspended Solids, Sulfate, Surfactants
          oTPH
          oVolatile Acids
          oZinc

The following Hach methods require extra rinsing when using the Pour-Thru Cell:

          oAluminum (Aluminon method)
          oChlorine Dioxide, LR (Chlorophenol Red method), Cobalt (PAN method), Copper (Porphyrin method)
          oHardness (Calmagite method)
          oManganese, LR (PAN method)
          oNickel (PAN method), Nitrate, MR and Nitrate, HR (Cadmium Reduction method)

If measuring Ammonia or TKN (Total Kjeldahl Nitrogen), clean the Pour-Thru Cell periodically by pouring a few sodium thiosulfate pentahydrate crystals into the cell. Let stand for a few minutes, then rinse well with deionized water.
