ROHS2.0special detector

Product introduction：

Rohs2.0 liquid chromatograph can provide fast analysis speed, high resolution, and keep the system low pressure to a great extent. Therefore, it retains the durability and working principle of conventional HPLC instruments and methods.

This design makes RRLC a general liquid analysis flow rate range, suitable for column size from 1 to 4.6-mm ID, column length from 10 to 300 mm, particle size from 1.5 to 10 μ M
