2 instruments and devices

2.1 Sampler 2.1.1 Material. stainless steel or plastic. 2.1.2 Size. inner diameter of 25mm ~ 30mm, opening width of 18mm ~ 20mm, the length of the opening is not less than the ion exchange resin storey 80% of degrees. As shown in Figure 1. The total length of the sampler can adjust the height of the exchange resin layer according to the container lon sampler probe into the bottom of the container opening paragraph After the trailing end of the surface layer is higher than the ion exchange resin is not less than 200mm. Note. The sub-sampler can be made to facilitate different ion exchange resin layer height of specimen sampling. Millimeters Figure 1 Sampler 2.2 points like container Flat enamel or plastic container. 2.3 sample container Clean sealable container.

3 Sampling Rules

3.1 Sampling We need resin samples from the same batch of ion exchange, when there are n the package, when n is less than or equal to 3.00 each sample shall not be less than 3; when n is greater than 3.00 to take a random sampling method, the total number of samples calculated according to the formula n 1 (whichever occurs decimals rounded up method Integer), each sample shall not be less than 2 times. ......
