Overview
This summary is a sampling list of what LEAP has done and can do for you. All of these are focused on getting you Higher Throughput
Specific Categories
There are many techniques and applications that LEAP can help you with to increase sample throughput with automated injection HPLC systems. From "Front Cuts" to "Heart Cuts" to "Back Cuts" to "Multiplexing". Typical applications are pre-column SPE, pre-column cleanup, sample desalting,parallel column regeneration, etc. LEAP has the experience to solve your throughput needs. These are just a few of our offerings. We integrate multiple vendors HPLC systems and have a wide array of injection valves and selector valves to get you the best result. Many of these can be added to your existing systems to better utilize the hardware you already have.
