Sofeware: Empower3 personal Single System Add-On


Detector name Scope of application Characteristic Detector
UV/VISWaters 2487 2489 Detection of most common UV-absorbing organic substances and some inorganic substances High sensitivity, low noise, wide linear range, and good selectivity
PDA/DADWaters 2996 2998 PDA Most compounds with UV absorption Scans full-wavelength chromatograms and spectra, chromatographic peak purity and qualitative properties of components
RIDWaters 2410 2414 Compounds that do not absorb light in the ultraviolet range, such as polymers, sugars, organic acids, and triglycerides, are detected. Universal detector with good sensitivity to detect compounds with low UV absorption
FLDWaters 474 2475 Detection of fluorescent substances, suitable for trace analysis of polycyclic aromatic hydrocarbons and various fluorescent substances. Derivatization can also be carried out to detect compounds that are themselves non-fluorescent High selectivity, only response to fluorescent substances; high sensitivity, minimum detection limit of 10-12ug/ml
ELSDWaters 2420 2424 Detection of compounds that do not contain chromophores, such as: carbohydrates, lipids, polymers, underivatized fatty acids and amino acids, surfactants, drugs, etc High sensitivity, no influence on mobile phase system
ELCDWaters 432 Detection of halogen, sulfur, nitrogen compounds High selectivity and high sensitivity
