Investing in a new liquid chromatography-mass spectrometry (LC-MS) system is a big decision, especially when your lab handles a wide variety of analytical tasks. With so many options out there, it’s easy to feel overwhelmed.

That’s where this blog comes in. We’ll walk you through the bioanalytical quantitation solutions offered by SCIEX, helping you better understand which system might be the best fit for your current needs and future ambitions.

SCIEX doesn’t offer a one-size-fits-all approach. There are several LC-MS systems, each with its own strengths. So, whether you’re focused on today’s workflows or planning for tomorrow’s challenges, there’s a solution that aligns with your goals.

Let’s dig into this in more detail because life is never this simple.

Routine bioanalysis

When it comes to bioanalysis, SCIEX has been a trusted name in quadrupole mass spectrometry for as long as most of us can remember. But it’s not just about the hardware. We’re proud of the reliability, support, and innovation that come with every LC-MS system we offer.

All our instruments run on SCIEX OS software, a powerful yet intuitive platform designed to simplify your workflow. Whether you’re working in a regulated environment or not, using compliance-ready software from the start can be a smart move. It helps streamline method development and makes future transitions into regulated bioanalytical spaces smoother and faster.

Here is an example of the performance you can expect from the system, Highly sensitive LC-MS/MS method for the quantification of fluticasone propionate in human plasma using the SCIEX QTRAP 6500 System

Routine bioanalysis requiring higher sensitivity

As technology has developed, mass spectrometers have become more sensitive and what was considered a nice-to-have feature is now often essential. If you need to see trace-level analytes or your matrices are very complex, the 7500+ system is the better option for you.

Flexible Quant/Qual system, more selectivity, or larger analytes

In the last 5 years, improvements in the quantitative performance and sensitivity of time-of-flight (TOF) technology has made it more attractive to bioanalysis labs. The ability to offer both quantitation and qualitative information on a single system makes life easier. Also, as drug modalities have changed and test compounds have become larger, they have exceeded the mass range of quadrupole systems making a TOF essential.

Additional benefits of a TOF are increased selectivity allowing low-level analytes to be distinguished from complex matrices. This can allow for shorter run times and reduced sample preparation.

Why traditional MS/MS falls short for ADCs and how electron-activated dissociation (EAD) changes the equation

Antibody-drug conjugates (ADCs) are among the most promising—and analytically demanding—modalities in biopharma today. By combining large, heterogeneous antibodies with chemically labile payloads and linkers, ADCs introduce a level of structural complexity that challenges conventional analytical workflows. It also poses the challenge that the very features you need to measure are often the easiest to lose during analysis.

Six benefits of remote support every laboratory should know

Imagine having a tech expert at your fingertips to solve computer issues or a fitness trainer guiding you through workouts from the comfort of your home. In today’s fast-paced world, the ability to provide and receive service and support remotely is no longer a luxury but a necessity. Whether it’s troubleshooting a software issue, repairing a device, offering customer assistance, or enjoying the convenience of telehealth as a private individual, remote capabilities have revolutionized how businesses operate and how individuals get help

The costly consequences of unplanned downtime

Unplanned downtime is a formidable adversary that businesses across various industries strive to minimize. Defined as the unexpected interruption of regular operations, unplanned downtime can wreak havoc on productivity, profitability and customer satisfaction. In this article, we delve into the causes of unplanned downtime, its far-reaching consequences and strategies to mitigate its impact.
