- High sensitivity for small sample sizes
- Compatible with LC/MS interfaces
- Wide variety of bonded phases
MicroBore (1 mm ID) columns are often a good choice when sample sizes are limited. They can improve detection limits 5 times over 2.1 mm ID columns when the same sample mass is used. This increase in sensitivity can be critical. MicroBore columns use low flow rates (typically ~ 50 µl/min). Therefore, these columns are ideal for use with detectors requiring low flow rates such as some mass spectrometers and with capillary LC systems.
MicoBore columns perform optimally with HPLC systems purchased or modified for microbore use. A wide variety of bonded phases are available for use up to 400 bar including StableBond SB-C18, SB-C8, 300SB-C18; Eclipse XDB-C18 and XDB-C8; Bonus RP, Extend C- 18; and Poroshell columns. Guard columns are also now available with an adjustable tube stop depth to provide a perfect zero dead volume connection every time. A selection of bonded phases are available in 1.8um and a higher pressure format.
