Integrated accessory automates sample measurement and injection volume adjustment


The Thermo Scientific


Dionex AS- AP Sample


Conductivity and pH Accessory is a


new optional feature


for the Dionex AS-AP autosampler streamlines IC workflows by automating conductivity and pH measurements before injecting samples onto an IC system with the help of Thermo Scientific Dionex Chromeleon conditional statements.


“The accessory completely automates inline,


pre-injection measurements of conductivity and pH,” said Evett Kruka, director of product marketing, IC/SP, Thermo Fisher. “It will save users considerable time and labour and provide much more consistent


results, compared to manual methods.”


The new


pH Accessory enables users


to confirm the integrity of their


samples in advance, which avoids wasting time running degraded samples and ultimately better protects their columns. Along with the conductivity and pH measurements, the accessory automates other pertinent parts of the measurement process, including calibration, sample injection decisions and processing and result reporting.

Chromatography medium for capture of antibodies and antibody fragments


GE Healthcare’s Capto L affinity chromatography medium (resin) is designed for the purification of antibody fragments. It combines a rigid, high-flow agarose matrix with the immunoglobulin-binding recombinant protein L ligand, which has strong affinity for the variable region of antibody’s kappa light chain. Capto L is therefore suitable for purification of


a range of antibody fragments such as Fabs, single- chain variable fragments and domain antibodies. With its high dynamic binding capacity and high


selectivity, Capto L increases process economy and process design flexibility.

High separating power for complex samples


The Agilent 1290 Infinity 2D-LC solution for comprehensive and heart-cutting two-dimensional separations has been launched. The instrument’s separating power is designed for highly complex samples such as biopharmaceuticals, peptide maps, plant extracts, food matrices, polymers and other very challenging mixtures. The new solution is based on the 1290 Infinity


binary pump and an innovative new 2D-LC valve. The system’s software enables configuration of 2D-LC methods in minutes. The system combines orthogonal HPLC separations into a single 2D-LC analysis so that peak capacities can multiply, offering substantial increases in separating power over conventional liquid chromatography. This makes 2D-LC the a suitable tool for highly complex samples requiring the highest separation power. “Until now, the setup of 2D-LC systems and methods has been tedious and time-consuming,” said Patrick Kaltenbach, Agilent vice president and general manager of the Liquid Phase Separation Business. The Agilent 1290 Infinity 2D-LC solution offers


highly flexible system setup using any 1260 or 1290 Infinity hardware in the first dimension and a 1290 Infinity binary pump in the second dimension. Agilent has also announced an agreement with


GC Image, LLC, to co-market the company’s GC Image LCxLC Edition software for analysis of comprehensive 2D-LC data.
