Bioinert Multiple Wavelength UV-VIS - P/N 404-2157

The (Bio)SECcurity² GPC1260 MWD is a dedicated multiple wavelength detector that offers the same high sensitivity for both single and multiple wavelength detection. Deuterium and tungsten lamps with a wavelength range of 190 to 950 nm offer an expanded detection range with lowest detection limit. The diode array based design enables simultaneous acquisition of up to 8 compound-specific wavelengths for increased sensitivity and selectivity. The MWD is ideal for protein characterization and for copolymer analysis using dual detection (for polymers with chromophores).

Diode Array Detector (DAD) - P/N 404-2110
Bioinert Diode Array Detector (DAD) - P/N 404-2156

The (Bio)SECcurity² GPC1260 DAD features a completely new optical design based on a Max-Light cartridge cell with optofluidic waveguides. Even under harsh and fluctuating ambient temperature and humidity conditions low detection limits are reached. Multiple wavelength and full spectral detection with up to 80 Hz data rates allows precise identification, quantification and purity analysis at trace levels.

The WinGPC UniChrom 3D Spectra module allow comprehensive analysis and presentation of the 3D-DAD data fields.

Light Scattering

Multi Angle Light Scattering Detector SLD7100 - PSS P/N 403-0013
Bioinert Multi Angle Light Scattering Detector SLD7100B - PSS P/N 403-0014

The SECcurity SLD7100 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/GFC system. The SLD7100 can be used in batch mode (off-line) without modifications. A bioinert version for hard conditions is available.

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

 

Multichrom Right Angle Light Scattering Detector SLD1000 - PSS P/N 404-2130
Bioinert Multichrom Right Angle Light Scattering Detector SLD1000B - PSS P/N 404-2158
Micro Multichrom Right Angle Light Scattering Detector SLD1000M - PSS P/N 404-2182

The (Bio)SECcurity² SLD1000 RALLS (RALS) is a right angle static light scattering detector for the measurement of absolute molecular weight of macromolecules in solution. The special feature of the PSS SLD1000 light scattering detector is that it is not shipped with a fixed wavelength but that the wavelength is selectable in the range 300 to 600 nm. Different cell options (analytical, bioinert, micro) are available, cells can be easily exchanged.
The detector design allows seamless integration into any PSS (Bio)SECcurity² or Agilent stack.

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

Viscometer

Viscometer DVD1260 - PSS P/N 402-0025
Micro Viscometer DVD1260M - PSS P/N
402-0026
The SECcurity DVD1260 four capillary viscometer combines low-noise electronics with high-sensitivity pressure transducers to result in excellent peak shapes and high signal linearity.

ELSD

Evaporative light scattering detector ELS1300 - P/N 409-0037
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.
