Bona Eirgil Recruitment

Agilent and Waters columns are commonly used. These two brands have relatively high market share and good response. In addition to the above two brands, we use more columns from Philemon and Bonaiger, and we also use domestic Ma Di columns. The effect is not bad, but it works well. I don't know how durable it is, and the price is not much cheaper. I just buy imported columns.
