SECcurity GPC1260 Refractive Index RI detector

SECcurity GPC1260 RI detector

The detector of  choice for the analysis of non-UV absorbing samples.

 

Ideal concentration detector for the combination with on-line light scatterging detectors or on-line viscometers.

 

The high signal-to-noise ratio is enabled by a minimum baseline noise. Electronic temperature regulation maintains a steady optical unit temperature up to 55° C resulting in a stable baseline.

Convenient early maintenance feedback (EMF) is available.

An automatic solvent recycle valve is already included.

SECcurity Evaporative light scattering detector ELS1400

SECcurity GPC1260 ELS detector

ELSD with superior and sensitive detection for a wide variety of chemical classes and structures. With ThermoSplit technology for the optimal signal to noise ratio. Low detection limits down to 5 ng. Low evaporation temperatures and outstanding reproducibility. No baseline shift even with extreme gradients.

The fully warranted Teflon nebulizer provides superior solvent and chemical resistance, eliminates sample build-up even at high temperatures, does not permit sample carry over or increased noise from surface leaching. Reproducible droplet distributions are assured by thermally isolating the nebulizer from the spray chamber and drift tube, improving reproducibility between methods.


Low gas pressure and flow requirements allows use of cylinder,

house systems, or gas generators. The pneumatic system is protected

by a high pressure shut off, and provides a signal in the event of

unstable or low pressure.

SECcurity on-line multi angle light scattering detector SLD7000(B)

SLD7000 7-angle MALLS

The SECcurity SLD7000 MALLS (MALS) is a 7-angle static light scattering detector for the measurement of absolute molecular weight, size, and conformation of macromolecules in solution. The revolutionary design with a cylindrical, self-cleaning, and index-matching cell avoids common pitfalls in GPC/SEC-light scattering detection. Modern ultra-sensitive CCD detection results in high sensitivity, even at low concentration and molar masses.

The small footprint allows integration into any GPC/SEC or FFF system.

The SLD7000 can be used in batch mode (off-line) without modifications.

In combination with an RI and a viscosity detector the light scattering
detector can be used for triple detection and triple plus detection.

SECcurity on-line viscometer DVD1260

SECcurity DVD1260 viscometer

The SECcurity DVD1260 four capillary viscometer lowers the detection limit with an asymmetric bridge design. While other viscometers dilute 50% of the sample in the solvent path, the DVD1260 dilutes only 20% of the sample in the solvent path. 80% of the sample run through the sample path leading to an unparalleled signal/noise ratio without any digital signal processing. Low-noise electronics combined with high-sensitivity pressure transducers results in excellent peak shapes and high signal linearity. The use of reservoirs (instead of hold-up columns) eliminate viscometer modifications when the column setup changes and reduces the analysis time to 50% compared with other viscometers. 

 


The SECcurity DVD1260 can be integrated into any GPC/SEC or FFF system.
