PAL MALDI Option General System Overview
The PAL MALDI Option micro collector/spotter is an add-on PAL module for micro scale fraction collection or MALDI Spotting together with any Capillary LC or Nanoflow LC system. The collection of very low volume fractions requires low delay volumes and high position accuracy of the capillary tip.
Abstract
Rapid and accurate identification and quantification of proteins is one of the goals of today's proteomics research. One key requirement for this approach is the ability to resolve the individual components of
peptide mixtures prior to MS analysis. The challenge is to achieve high sensitivity with limited sample amount. This requires equipment that is specifically designed for separation at low flow rates and that allows
the collection of small fraction volumes, even on MALDI targets.
The micro collection/spotting system PAL MALDI Option meets this challenge. It is an ideal tool for single or multidimensional chromatographic separation of complex peptide and protein mixtures for subsequent analysis by MALDI and/or ESI mass spectrometry. The offline combination of LC separation with MALDI MS analysis gives scientists significant advantages over the widespread online ESI/MS approach. LC/MALDI “freezes” the LC separation on the MALDI plate and allows MS/MS experiments without any time constrains. Intelligent decisions can now be made during analysis, allowing results-driven analysis without rerunning the sample. Decoupling the separation from the analysis gives the opportunity to optimize the separation performance and the total sample throughput.
Flexibility for LC/MALDI spotting on various target types from different vendors as well as collection into well plates (96 and 384). Probe positioning control of 0.1mm enables reproducible and robust collection of small fraction volumes from nl to the lower μl range. Matrix addition can be done either offline or online by premixing the matrix with the eluent. A Peltier cooling option prevents thermal decomposition and evaporation of the micro fractions. Intelligent hardware design guarantees lowest delay volumes down to a few nl to achieve optimal chromatographic resolution.
