SCIEX micro cHiPLC columns decrease column run times and increase sample throughput with a larger diamer 200 μm ID format. The 200 μm ID cHiPLC columns allow samples to be run at higher flow rates and therefore with higher throughput. The larger diameter column also provides increased robustness, ease of use, and sample loading capacity over traditional 75 μm ID nanoflow LC. For many applications, the 200 μm ID format provides just the increase in speed and throughput that your research demands - all in a simple cHiPLC column.
Because of its high sensitivity, nanoflow liquid chromatography coupled with mass spectrometry (nanoLC MS) is the method of choice for many biological research applications. However, the low flow rate of nanoLC reduces sample throughput due to gradient delay in the nanoLC system itself, delay in the autosampler and sample loop, and the delay caused by the connecting tubing. One way to address this is to use a larger inner diameter column at a proportionally higher flow rate. While this will reduce sensitivity when the total sample amount is kept equal, the delay times can be greatly reduced and sample throughput accelerated. Reducing the column and gradient lengths can further reduce the analysis time required per sample.
SCIEX 200 µm ID micro cHiPLC columns for the cHiPLC-Nanoflex offer the perfect solution for those applications demanding higher sample throughput and faster analysis times. SCIEX micro cHiPLC columns are made with the same dedication to manufacturing quality and innovative engineering as our nano cHiPLC columns.
Special care has been given to the design of both the trap-chips and analytical column-chips in order to achieve separations that are equal or better than separations obtained using packed capillaries. The use of fused silica allows for cylindrical channels for packing columns and traps. Instead of conventional frits made out of fused stationary phase particles, our cHiPLC columns use a unique weir structure to retain the stationary phase particles in the column. These weirs are more reproducible to fabricate, while their dead-volume is virtually zero (~13 pL). In addition, adsorption of sample components that can occur with frit material is not an issue with these types of structures.
Patented connection system
Connections to and from each chip are made using a patented connection system that can connect up to seven channels to the outside world with a dead volume of less than 1 nl. The force used to connect the chip is pre-set, so that every time the user exchanges a chip, a leak-free connection is obtained without any required user adjustments.
Increased column-to-column reproducibility
Besides the ease of replacing a column or trap in seconds, the use of our cHiPLC columns also increases column-to-column reproducibility. All chips are exactly identical, and our packing procedure guarantees the best possible column-to-column reproducibility. This is of importance for applications where retention time stability over longer periods of time and over multiple columns is important. Examples are the use of retention time in combination with accurate mass in peptide/protein identification and scheduling MRM's for peptide quantitation in biomarker verification.
Micro cHiPLC columns and trap columns are available in several different stationary phases and column lengths.
