Determination of Three Plant Growth Regulators in Fertilizers by Gas Chromatography
Determination of 3 Plant Growth Regulators in Fertilizers by Gas Chromatography Details:

Name: capillary column
Stationary phase: 5% phenyl-methyl polysiloxane
Specifications: 30m*0.32mm*0.25um
Model: HH-5

This document describes a gas chromatographic method for the determination of the plant growth regulators diethyl aminoethyl hexanoate, paclobutrazol in fertilizers.
This document is applicable to the detection of diethyl aminoethyl hexanoate and paclobutrazol in fertilizers.
The detection limit of diethyl aminoethyl hexanoate and paclobutrazol in the determination of water-soluble fertilizer products by the method in this document is 10 mg/kg, and the limit of quantification is 30 mg/kg. mg/kg with a limit of quantification of 7.5 mg/kg.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a gas chromatography analysis method for three plant growth regulators in fertilizers by comparing the extraction effects of different extraction solvents on plant growth regulators.
[Method] The samples were ultrasonically extracted with acetone, separated by HH-5 capillary gas chromatography column, and detected by FID detector.
[Result] The mass concentrations of the three plant growth regulators were linearly related to the corresponding peak areas in the range of 5-100 mg/L, the correlation coefficient was r0. When the sample size was 0.5 g, the detection limit of the method was 10 mg/kg.
[Conclusion] The method is simple and fast for sample pretreatment, and the repeatability and recovery rate can meet the requirements of detection and analysis, and can be applied to the detection of plant growth regulators in fertilizers and medicinal fertilizers.
