High selectivity is a key component of successful quantitative bioanalysis. As a bioanalyst, we need consistently accurate and robust quantitation of small molecule therapeutics and metabolites. Challenged by complicated matrix interferences, high baseline signal, and lack of isomer resolution, we need to embrace innovative strategies to increase the sensitivity and selectivity of our assays. If our ‘go-to’ is the development of complex HPLC conditions or modifying sample preparation procedures, we will find ourselves bogged down with time-consuming methods that reduce sample throughput. So, what’s the answer?
Imagine a new dimension in bioanalytical selectivity that you never thought possible. One that enables robust and reproducible bioanalytical methods, and meets high throughput requirements. One that reduces background noise, eliminates interferences and separates highly similar compounds, without having to resort to complex HPLC conditions or sample workup procedures.
Well this could very much be your reality.
Significant advances have been made in increasing MS/MS selectivity beyond the gold standard MRM. For example, MRM3 on the QTRAP® systems adds additional selectivity by increasing the number of fragmentation steps by the mass analyzer. Ion mobility presents another attractive option by introducing an orthogonal level of separation after sample ionization, followed by traditional m/z detection.
Although ion mobility techniques have been used extensively for qualitative applications, they have traditionally lacked the required ruggedness and speed required for quantitative bioanalysis. Not anymore, and hereby the end of the history lesson!
SelexION® DMS Technology provides an orthogonal level of separation. It is the first differential ion mobility separation technology to combine sensitivity and selectivity with unmatched reproducibility and robustness. It delivers enhanced analytical separations on demand for isobaric species and co-eluting contaminants, all in an elegantly simple package.
Along with the QTRAP 6500+ or 5500 systems, you get the power of differential ion mobility separation, enabled by multiple new innovations in ion mobility:

In your lab, time is not just a resource. It’s a necessity and every moment counts. Yet, unplanned downtime can disrupt this delicate balance. Even a brief interruption can set your team back in multiple ways.
In a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
Whether we are raising glasses of rosé in a vineyard in France or enjoying a lager in a casual street restaurant in China, it is likely that the last thing on many people’s minds is the chemical risks from their beverage. Unless you work in food science, then it might actually be the first thing.
