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 viscometer ETA2010

SECcurity ETA2010 on-line viscometer

The SECcurity ETA2010 viscometer 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 ETA2010 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 ETA2010 can be used with any GPC/SEC system. The use of reservoirs in the bridge eliminate viscometer modifications when the column setup changes and reduces the analysis time to 50% compared with other viscometers.

The SECcurity ETA2010 can be integrated into any GPC/SEC or FFF system.
