PharmaFluidics’ μPAC capLC is evaluated for different user needs ranging from 12 samples per day in comprehensive mode to 65 samples per day in throughput mode.

PharmaFluidics introduces a new μPAC capLC column that offers unprecedented performance and that given its low backpressure can be used with flow rates of up to 15μL/min.

PharmaFluidics’ μPAC capLC is evaluated for different user needs ranging from 12 samples per day in comprehensive mode to 65 samples per day in throughput mode.

Overall gain in performance and increase in detection sensitivity that can be achieved for the separation of plant metabolite extracts by using µ¬PAC columns.

PharmaFluidics also offers a 50 cm long μPAC column which is perfectly suited to perform more throughput analyses with shorter gradient solvent times.

Analyzing skin ceramides using PharmaFluidics’ µPAC column technology reveals a substantial structural diversity and isomeric resolved sphingolipids.

Monitoring the excellent separation performance of PharmaFluidics’ µPAC columns by using peptide retention time calibration mixtures for bottom-up proteomics.

PharmaFluidics’ μPAC columns have the potential to be less prone to sample related column failure and to withstand more sample injections without losing performance.
