键合度 meaning in Chinese

degree of bond

When injecting samples , chromatographic column should be completely flushed and balanced with mobile phase ; if the system applicability is not up to regulation , or if filling agents are damaged , replace with new similar chromatographic column for analysis ; if operation according to procedures can not reach scheduled separation due to existence of certain difference between degree of bond of chemically bonded - phase of similar filling agents and performance , another brand of similar chromatographic column can be used for test
3进样前，色谱柱应用流动相充分冲洗平衡，如系统适用性并不符合规定，或填充剂已损坏，则应更换新的同类色谱柱进行分析，由于同类填充剂的化学键合相的键合度及性能等存在一定差异，往往依法操作达不到预定的分离时，可更换另一牌号的同类色谱柱进行试验。
