GL Sciences olfactory detection system for GC or GC-MS PHASER Pro
A temperature-programmable transfer line is introduced in this instrument that can be programmed as the GC oven. This results in a stable split ratio (sniffing flow rate/detector flow rate). Heat stress at the nose and thermal degradation of the compounds are prevented, making it possible to perform olfactory detection with higher accuracy and sensitivity.

Rapid gravity separation of two phase systems using ISOLUTE phase separator columns and 96-well plates
This chemistry data sheet describes the use of ISOLUTE phase separator columns and 96-well plates to separate aqueous solutions from chlorinated organic solvents.

Biotage organic chemistry products
Organic chemists synthesizing new molecules follow a general workflow. Biotage has developed tools for every step of the process, with the entire workflow in mind. This dedicated suite of products vastly expands the range of options in order to truly accelerate discoveries of new molecules for future innovations.

Biotage Sfär columns
Reliable and flexible, Biotage Sfär columns deliver larger loading capacities, tighter elution bands and purer fractions than traditional flash columns.

A simple setup to use semi-preparative HPLC columns on Biotage Selekt
The Biotage Selekt can be run at a maximum flowrate of 300 mL/min or a maximum pressure of 30 bar. These high flowrates and pressures enable a user to perform chromatography using not only dry-packed, single-use plastic flash columns containing small (≥20 um) spherical silica particles, but also semi-preparative, slurry-packed HPLC columns for multiple use with smaller (≤20 um) spherical silica particles.

TF3 with MALS and viscometer – comprehensive two-dimensional polymer separation with advanced detection
Thermal field-flow fractionation (TF3) is a powerful technique for the separation of large or complex polymer samples. When used in conjunction with advanced detection systems such as multi angle light scattering (MALS) and viscosity, it is an indispensable tool to gain deeper insight into the nature of these complex polymer samples.

Separation of nanoplastics and determination of their surface charge by EAF4
In this application note, Postnova presents data on separation of polystyrene nanoplastics, and demonstrate how electrical asymmetrical flow FFF (EAF4) can be used for simultaneous size separation and particle surface charge measurement.

Quantification of adeno-associated virus aggregation using asymmetrical flow field-flow fractionation
In this application note, Postnova presents data on separation of AAVs and their aggregates using asymmetrical flow field-flow fractionation (AF4) and measurement of their radius of gyration (Rg or root mean square radius, R.M.S.) by multi angle light scattering (MALS).

Sizing of polydisperse silver nanoparticle suspensions - comparison of AF4 coupled to online DLS with batch mode DLS
This application note presents a comparison of DLS in batch mode with asymmetrical flow field-flow fractionation (AF4) coupled with DLS (AF4-DLS) for the measurement of a mixture of silver nanoparticles (AgNP) of different sizes (20 nm, 40 nm, 60 nm).

Measurement of cancer biomarker enrichment in exosomes: separation using both AF4 and CF3
In this study the goal was to characterize the MCF-7 tumor exosome sample by size using asymmetrical flow field-flow fractionation (AF4) coupled to multi angle light scattering (MALS), and by mass using centrifugal field-flow fractionation (CF3).
