Next-Generation Mass Spectrometers
High-quality results faster, and with less effort

The Xevo TQ-S and Xevo G2 QTof are the newest additions to Waters’ Xevo family of mass spectrometers, offering high levels of sensitivity for compound identification, quantification and screening.

Xevo TQ-S allows the user to quantify compounds at concentrations lower than previously possible. It features an innovative ion source—StepWave™—which is constructed from two stacked ring electrode devices to provide a single, off-axis ion transfer lens. The diameter of the sampling cone’s orifice is almost twice that of previous models, increasing the number of ions that enter the mass spectrometer.

“This design ensures that any neutral sample matrix contamination… is actively extracted from the system,” said Dr. David Little, senior product manager for Quadrupole MS at Waters Corporation. “Ensuring that key elements remain clean and providing long-term robust operation.”

The Xevo G2 QTof exact mass MS/MS mass spectrometer features Waters QuanTof™ technology, which can extend the dynamic range of previous generation Xevo QTof systems to greater than four orders of magnitude. It incorporates UPLC/MSE, a simple method of data acquisition that catalogs complex samples in a single analysis, providing users with a complete record of the sample, allowing him/her to bring it up again at any time.

“The latest Xevo instruments provide… performance benefits,” added Dr. Little. “Whilst maintaining the simplicity of operation associated with the Xevo family.”

Pfeiffer Vacuum


Variable Speed Rotor Mill
All-Purpose Mill for Medium-Hard to Soft Substances

PULVERISETTE 14 from Fritsch is an all-purpose mill for rapid crushing of medium-hard, brittle and fibrous samples. It can also be used to disperse and homogenize dry samples. Difficult samples, including polyester, PVC and styrene, can be ground to analytical fineness by process of embrittlement (adding liquid nitrogen before grinding).

The mill features impact bars for grinding temperature- sensitive materials. “This avoids shearing of the material between rotor and sieve,” said Simon Wolfgang, sales manager at Fritsch. “A special design of the disk below the rotor ensures a constant airflow to cool the rotor and the grinding material. This is especially necessary for some polymer samples.”

A large fan blows cooled air into the instrument through a foam particle filter to create positive pressure that prevents the penetration of dirt particles from the ambient air.

The mill features a top speed of 20,000 rpm and a feed size of

Single-Use Bioreactor
Moving Sparger Provides Enhanced Gas Exchange

The Integrity™ PadReactor™ from ATMI Lifesciences combines portability with simplicity to provide a bioreactor that offers features available on larger, stationary units. The scalable, efficient bioreactor can be installed in less than an hour, and its single-use technologies provide an economic benefit over stainless steel systems.

The PadReactor system incorporates key proprietary elements, including Integrity TK8 film polymer, which is animal-derived component free (ADCF), integrity tested and gamma irradiated. The system also provides enhanced gas exchange, due to a moving sparger, and low shear mixing due to the vertices of the square tank, which act as natural baffles.

“Designing a square tank affords more efficient mixing and gas transfer,” said Roman Rodriguez, global product manager, Bioreactors, ATMI Lifesciences. “The square design also means a better exchange surface area, allowing better CO2 stripping and thus a more stable process over the batch.”

With the ability to accommodate a range of volumes from 20 liters to 1,000 liters, the PadReactor boasts many cost-efficient features, such as reduced power and validation requirements. It also comes with a compact footprint; the 25-250 liter model stands at 1.17 m2 while the 500-1,000 liter size occupies 2.4 m2.
