What is QDa in mass spectrometry?
The ACQUITY QDa Detector is the mass detector designed as a synergistic element of your chromatographic separations system. Minimize the risk of unexpected co-elutions, and you will be able to confirm trace components with certainty because of the analytical confidence of mass detection.
What is TUV detector?
The Waters® ACQUITY™ UPLC™ Tunable UV (TUV) Detector is a tunable, dual-wavelength UV/Visible (UV/Vis) detector specifically designed and optimized for the entire line of ACQUITY UPLC systems. The ACQUITY UPLC TUV Detector maintains its low-noise electronics and support for sampling rates up to 80 points/s.
What is rid detector?
A differential refractometer (DRI), or refractive index detector (RI or RID) is a detector that measures the refractive index of an analyte relative to the solvent. They are often used as detectors for high-performance liquid chromatography and size exclusion chromatography.
WHAT IS A DAD detector in HPLC?
Diode-Array Detection (DAD) or Photodiode-Array Detection (PDA) is an analytical technique that can be used to determine the purity of an analyte or related impurity peak eluting during an HPLC separation. The diode array detector uses the same principles of operation as a variable wavelength detector (VWD).
What is tunable UV detector?
The ACQUITY UPLC TUV Detector is a tunable, dual wavelength ultraviolet/visible (UV/Vis) detector that offers optimal linearity, resolution, and sensitivity for UPLC/UV separations.
What is electrochemical detector?
Electrochemical detection is a powerful analytical method that can detect electric currents generated from oxidative or reductive reactions in test compounds.
What is the difference between UV and DAD detector?
The UV/Vis detector can detect single wavelength at one time while the DAD can scan a wavelength range (i.e. 190-800nm). But DAD is better than UV/Vis because it can scan whole 190-800 nm region, on the other hand, UV/Vis can scan a single wavelength only.
What is difference between PDA and DAD?
The HPLC/UV generally only measures a couple of user-selectable specific wavelengths simultaneously. The photo diode array (PDA), also known as the diode array detector (DAD) can measure the entire wavelength range in real time, which may provide other advantages.
What is an Acquity QDA detector?
The Waters ACQUITY QDa Detector is a mass detector built around the needs of analytical scientists for chromatographic analysis. Robust, reliable and requiring no sample adjustments, it just integrates with your current LC, ACQUITY UPLC, ACQUITY UPC2, and purification systems.
What should I do if my QDA is leaking into the atmosphere?
If the instrument is a standard QDa fitted with a diaphragm pump, assume an additional 0.5% maximum leak into the laboratory atmosphere. Warning: To avoid exposure to toxic substances and biohazards from O-ring leaks in the source exhaust system, observe these precautions: • Replace the source O-rings at intervals not exceeding one year.
