L-column HB 120Å Series
The demand for LC/MS is increasing in the field of medicine and environmental sciences. Trace analysis is often required in these fields. However, it is difficult to inject a large volume sample because the semi-micro column has a small diameter. Although a largevolume sample could be injected using the column-switching method, exclusive equipment, complicated operation, and complicated maintenance management are required. L-column HB is packed up to one column with the packing material for concentration and for analysis at a hybrid, and it demonstrates power for high-sensitivity analysis because of the large volume (more than 100mL) of the sample injection.
