Product introduction

Application

The method is suitable for the rapid detection of monosodium glutamate in gourmet powder.

Specification: 25 times.

Storage: normal temperature, avoid from sunlight.

Packaging: monosodium glutamate determination solution: 2 bottles, MSG agent: 1 bottle.

Period of validity: 12 months.

Usage

Measure the monosodium glutamate 0.2g to 10 mL colorimetric tube, plus pure water dissolved and diluted to 10.0mL scale, cover plug after mixing, and 2.0mL into 100mL Erlenmeyer flasks, join 10.0mL formaldehyde solution, adding 60mL water, add 4 drops of indicator, strain with monosodium glutamate determination of liquid dropping bottle upright titration to appear blue., recording titration of fluid consumption drops, the sampling quantity invariable situation, each set liquid drops is equivalent to 2.375% grams of sodium glutamate to calculate its content, at the same time the parallel blank titration samples, and in the computation of sample content by blank solution drop number.

Announcement

1. Titration bottle orthostatic attention so as to reduce the error.

2. Methods for the determination of the results with the sample label values differ by 2 or 3 drops of constant liquid, consideration should be given to the site operation errors, for non compliance should be sent to the laboratory samples for precise quantitative test.
