Abstract
The utility model is an ion-selective electrode which is used to determine the nicotine. The ion-selective electrode includes an electrode bar, an internal solution, and silver / silver chloride, and is characterized in that: the bottom of the electrode bar is disposed with a layer of sensitive material. The ion-selective electrode is a key component in the determinator, and the mathematics expression of correlation between the target substance concentration and electrode current can be obtained after determination through the sensitive membrane plated on the electrode, thereby the purpose of accurate, rapid and quantitative can be achieved, and the determination of the chemistry components needed to determine can be completed, that is the nicotine content in tobacco leaf. The utility model has low electric consumption, convenient determination, high precision, as well as easy operation, and can be used in field and headland directly, and then the fertilization methods can be adjusted in proper time and the harvest time can be determined through the determination results.
Description
Technical field
The utility model relates to and is used for the ion-selective electrode that tobacco leaf is measured nicotine.
Background technology
At present, 40 grades of grade scales of traditional tobacco leaf in the process of weighing the quality of tobacco quality, mainly are conceived to the outward appearance of tobacco leaf.And this quality grading standard of 40 grades can not be that this grade scale solves the problem that belongs to chemical scope with physical index for cigarette enterprise provides sound tobacco on the practical significance, reason.The inherent chemical index of tobacco leaf of only responding has quality, quality that could real reaction tobacco leaf.And to the assay method of the inherent chemical index of tobacco leaf, main at present chemical classical analysis method and two kinds of methods of stratographic analysis of adopting, these two kinds of methods all can only be finished under certain experimental situation, and experimental technique complexity, apparatus expensive, length consuming time are promoted the use of chemical index tobacco leaf deciding grade and level system for tobacco purchasings at different levels and administrative authority and are caused very large difficulty.
Summary of the invention
The purpose of this utility model provides a kind of ion-selective electrode of using mensuration nicotine used in the fast measuring instrument of multiple electrochemical sensor.
The technical solution of the utility model is: ion-selective electrode comprises electrode stem, internal-filling liquid and silver/silver chloride, it is characterized in that being provided with one deck sensitive material in the bottom of electrode stem.Sensitive material can adopt the PVC film.
Using ion-selective electrode of the present utility model is critical component in the analyzer, by the sensitive membrane on the electrode degree, obtain target substance concentration and electrode current correlativity mathematic(al) representation after measured, thereby reach the purpose of accurate fast quantification, finish the chemical composition that mensuration need be measured, i.e. nicotine content in the tobacco leaf.Its power consumption is little, measure easy, the precision height, easily operation can be directly used in the field and measure, and adjusts fertilizing method in good time and determines to receive and adopt the time by measurement result.
Description of drawings
Fig. 1 is an electrode structure synoptic diagram of the present utility model.
Among the figure, 1-silver/silver chloride, 2-internal-filling liquid, 3-electrode stem, 4-sensitive material.
Embodiment
Embodiment: as shown in Figure 1, ion-selective electrode of the present utility model is by electrode stem 3, internal-filling liquid 2, silver or silver chloride 1, and one deck sensitive material 4 that the electrode stem bottom is provided with constitutes (electrode stem 3 in the electrode, internal-filling liquid 2, silver or silver chloride 1 are prior art).Sensitive material is selected the PVC film for use.
Claims (1)
1, a kind of ion-selective electrode that is used to measure nicotine comprises electrode stem, internal-filling liquid and silver/silver chloride, it is characterized in that being provided with one deck sensitive material in the bottom of electrode stem.
