Vanquish DAD features
- Industry leading linearity with up to 2.7 AU
- Reduced interfering refractive index and thermal effects means less baseline drift and more reliable peak integration.
- Data acquisition at rates up to 250 Hz using up to 10 absorption channels and one spectral field delivers the best support of ultrafast separations.
- Easy-to-use detector with intuitive user interaction, convenient flow cell and lamp usage tracking, and the integrated wavelength validation through holmium oxide filter.
