SAMPLE PREPARATION FOR MALDI IMAGING
MALDI IMAGING AND CONTINUOUS SPECIMEN COLLECTION
When using micro or nano-HPLC for the separation of the sample components in a sample and they are in the same manner as the isolated fractions, such as in analytical HPLC. In many laboratories, the fractions are then collected in microtiter plates (MTP) or spotted on MALDI-MS targets plates for further studies.
The SunCollect MALDI spotter provides excellent performance for collecting fractions for both approaches. If desired, a single fraction can be collected in both formats through the unique “Dual Needle-Splitter” design simultaneously.
In this approach, the majority of the fraction is collected in the microtiter plate and a small proportion of the volume on the MALDI target including matrix solution are spotted. Even if the volume of fractions is large, the whole fraction can be collected and no eluant is lost.
The software is designed so that it is extremely easy to use. Very comfortable new sampling protocols or new target formats can be entered.
The SunCollect MALDI spotter is biocompatible, since the sample and collected fractions coming into contact only with PEEK and quartz.
