I. Product Overview

The HD-LHW4 sulfide acidification blowing apparatus: sulfides in the water sample are acidified and the generated hydrogen sulfide is carried by carrier gas (nitrogen) into an absorption bottle/tube where it is absorbed by an absorbing solution (zinc acetate-sodium acetate or 2% sodium hydroxide). The corresponding analytical method is then used to determine the absorbed sulfide ions. Developed per the 2022 new national standard HJ 1226-2021 (Water quality – Determination of sulfides – Methylene blue spectrophotometric method, iodometric method), it meets the sample-pre-treatment needs for water sulfide determination.

II. Key Features

Large-capacity reaction flask for simultaneous processing of multiple samples.

Hydrochloric-acid port, gas inlet and outlet are integrated in three separated openings that do not interfere with each other.

Constant-temperature water bath with a fast auto temperature-control system; heating temperature can be set manually.

A lift-position fixing knob adjusts the sample rack and gas-distribution system; the rotating sample rack is front-loaded for convenient operation.

Each sample's nitrogen flow is independently controlled or shut off; a needle-valve flowmeter accurately controls and displays total gas consumption.

III. Executive Standard
