Bulk house detectors are one of the most universal detectors for HPLC because they measure Attributes common to all analytes by measuring discrepancies in the cell section with and with no sample. Among the most popular bulk home detectors is definitely the RI detector. Supplied the common character of bulk property detectors, they reply to all analytes, placing much more emphasis within the selectivity on the chromatographic column.
