从水中浓缩病毒的暂定标准方法（TSM）固有的缺陷可以通过某些程序修改来克服或避免。可通过在吸附前向自来水中添加多价阳离子盐来克服可溶或胶体自来水成分对病毒吸附到过滤器表面的干扰。使用替代吸附剂过滤器可以避免现有TSM的几个困难。最后，使用替代洗脱介质可以显著增强碱敏感病毒类型的洗脱。包括17个参考文献和表格。

Deficiencies inherent in the tentative standard method (TSM) for concentrating viruses from water can be overcome or circumvented by certain procedural modifications. Interference by soluble or colloidal tap water components with the virus adsorption to the filter surfaces can be overcome by the addition of polyvalent cation salts to the tap water before adsorption. The use of alternative adsorbent filters can circumvent several difficulties with the present TSM. Finally, elution of alkali-sensitive virus types can be markedly enhanced by the use of alternative eluent media. Includes 17 references, tables.
