Abstract
The utility model discloses an automatic controller of constant temperature thin-layer development, being applied to a thin-layer chromatographic analysis and providing an automatic constant-temperature developing chamber. The automatic controller can provide a constant developing chamber temperature for a thin-layer chromatogram at all seasons according to the need of the analyzing work and can optionally determine the end-point of the thin-layer development through a turn button, having the function of end-point alarm and automatic stopping development. Thus, the utility model raises the precision and the work efficiency of the thin-layer chromatographic analysis and is favorable for the thin-layer chromatographic analysis to develop toward the direction of the instrument.
Description
The utility model relates to a kind of Development of Thin-Layer Chromatography apparatus for automatic control that uses in analytical chemistry.
The thin-layer chromatography technology is a kind of method for separating and analyzing to biased sample.In the expansion process of thin-layer chromatography, the height of temperature is very big to the migration velocity influence of sample point, and in order to reach the separation of repetition, development chamber requires to have stationary temperature.In addition, in the thin-layer developing process, must often observe and launch terminal point; If analyst's inadvertent may be launched excessively, cause certain loss can for working time and analytic sample.
Present domestic thin-layer developing is finished in the simple glass chromatography cylinder, the thin-layer developing automaton that does not also address the above problem.(ALLTECH AssOCIATEs INC.) provides a kind of thin-layer chromatography hummer (TLC BUZZER BOX), only the Development of Thin-Layer Chromatography terminal point is had warning function, and it does not possess constant temperature and stops launching function automatically in U.S. Kodak company.
The purpose of this utility model provides a kind of improved Development of Thin-Layer Chromatography self-actuated controller.No matter be summer or winter, it provides a certain stationary temperature for the Development of Thin-Layer Chromatography process, and provides warning according to the expansion terminal point that the analyst determines, stops expansion process simultaneously automatically.
The purpose of this utility model is achieved in that the constant temperature development chamber that has designed a special use for Development of Thin-Layer Chromatography, is reached the purpose of constant temperature by temperature-adjusting circuit control thermoelectric refrigeration of semiconductor piece; Detect the light difference in Development of Thin-Layer Chromatography forward position in addition by light activated element, send chimes of doom by warning circuit then, control motor or electromagnet simultaneously and thin layer plate is mentioned automatically leave the expansion solvent, expansion process is stopped.
The utility model has been designed the development chamber with laminated heat-preserving, dispose in the interlayer can temperature control the thermoelectric refrigeration of semiconductor piece; Design photosensitive control circuit and corresponding warning circuit and mechanical lifting mechanism in addition, so realize the requirement of constant temperature, warning and lifting thin layer plate easily.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the side cutaway view that launches self-actuated controller according to the thin layer constant temperature that the utility model proposes.Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This device is formed the development chamber (8) of a sealing by metal-coating (1), inner casing (2) interlayer and a double glazing panel (9).Face glass (9) can be opened, and is convenient to operation and observation.Near inner casing (2) thermal sensing element (5) is arranged in the interlayer, guide control thermoelectric refrigeration of semiconductor piece (4) to make development chamber (8) reach constant temperature by it.There is a bar shaped double glazing light inlet window (7) at the development chamber rear portion.External light (among the figure shown in the arrow) arrives light activated element (16) by face glass (9), flass plate (6), light inlet window (7).Light activated element (16) can be moved up and down the position of determining according to need of work by turn-knob (13) and pulley (17).
After thin layer plate (6) that needs launch is placed on the hanger (10) developping agent groove (3) in, developping agent climbs on thin layer plate (6), when rising to certain altitude, both light activated element (16) front ends, light activated element (16) induces the light difference in Development of Thin-Layer Chromatography forward position at once, signal is passed to warning circuit at once and send chimes of doom 1 actuating motor (14) simultaneously, rotating cam (15), (perhaps drive magnetic) upwards promotes vertical rod (12) and cross bar (11), mention hanger (10) and lift thin layer plate (6) by hanger, make thin layer plate leave developping agent groove (3), stop expansion process.
Whole development chamber device is fixed on the base (20) by a pair of support screw (18) and feet (19), the angle of 0-45 ° of development chamber device inclination can be convenient to operation and expansion.
Claims (4)
1, the thin layer constant temperature that is applied in the thin-layer chromatographic analysis launches self-actuated controller, this controller has a closed development chamber (8), it is characterized in that development chamber is made up of overcoat (1) and inner casing (2) and an openable double glazing panel (9), semiconductor temperature-difference refrigerating piece (4) is arranged in the interlayer, there is a stripe shape double glazing light inlet window (7) at development chamber (8) rear portion, near light inlet window (7) photosensitive part (16) is arranged, stood up a metal suspension bracket (10) in the development chamber.
2, device according to claim 1 is characterized in that light activated element (16) moves up and down near light inlet window (7) by turn-knob (13) and pulley (17).
3, device according to claim 1 is characterized in that suspension bracket (10) hangs up on cross bar (11), by the driven by motor cam or by the solenoid actuated knee-action.
4, according to the described device of claim (1), it is characterized in that controller is fixed on the base by a pair of support screw (18) and feet (19), controller can recede 0 °～45 °.
