Abstract
Present invention is disclosed evaporation photodetector cleaning agent, include the components of following parts by weight, trifluoroacetic acid 10% 13%, isopropanol 28% 32%, ethanol 29% 34%, surplus is water.The present invention realizes cleaning performance and corrosivity is low, protects instrument.
Description
Technical field
The invention belongs to technical field of chromatographic analysis, more particularly to a kind of evaporation photodetector cleaning agent.
Background technology
It is common detector to evaporate photodetector, can detect the organic substance of no UV absorption, such as ginseng soap
Glycosides etc., evaporates optical characteristics of the response independent of sample of photodetector, and any volatility is less than the equal energy of sample of mobile phase
It is detected, is not influenceed by its functional group.It is directly proportional to the quality of sample to evaporate the response of photodetector, thus can be used to survey
The purity or detection unknown material of random sample product.
Evaporation photodetector finds that atomizer arrangement easily pollutes setting and blocked in actual use, drift tube, light
Pond, and tail pipe, it is particularly easy to pollute in use for some time, therefore can be interfered during natural products is detected；
Pollutant some is dissolved in water, and what is had is not soluble in water, can generally be cleaned with organic reagent, some adsorption capacities need more by force
With acid lotion；Dust technology is needed to use to be cleaned by ultrasonic in the regular maintenance of instrument, maintenance time is longer, while dust technology
With certain corrosivity, instrument is damaged.
The content of the invention
The invention aims to solve above-mentioned technical problem, and a kind of evaporation photodetector cleaning agent is provided, from
And realize cleaning performance and corrosivity is low, protect instrument.In order to achieve the above object, technical solution of the present invention is as follows：
Photodetector cleaning agent is evaporated, includes the component of following parts by weight, trifluoroacetic acid 10%-13%, isopropanol
28%-32%, ethanol 29%-34%, surplus are water.
Specifically, the trifluoroacetic acid is 12% by weight percentage.
Specifically, the isopropanol is 30% by weight percentage.
Specifically, the ethanol is 31% by weight percentage.
Specifically, the cleaning agent is used for the residual of atomizer, drift tube, light pond and the tail pipe cleaned in evaporation photodetector
Stay thing.
Compared with prior art, present invention evaporation photodetector is mainly reflected in the beneficial effect of cleaning agent：Using clear
Lotion each component ratio, cleaning temperature is moderate, greatly shortens the cleaning used time, reduces the damage to instrument.
Embodiment
Clear, complete description will be carried out to the technical scheme in the embodiment of the present invention below, it is clear that described implementation
Example only part of the embodiment of the present invention, rather than whole embodiments.
Embodiment 1：
The present embodiment is evaporation photodetector cleaning agent, includes the component of following parts by weight, trifluoroacetic acid 10%, isopropyl
Alcohol 32%, ethanol 34%, surplus are water.
Embodiment 2：
The present embodiment is evaporation photodetector cleaning agent, includes the component of following parts by weight, trifluoroacetic acid 13%, isopropyl
Alcohol 28%, ethanol 29%, surplus are water.
Embodiment 3：
The present embodiment is evaporation photodetector cleaning agent, includes the component of following parts by weight, trifluoroacetic acid 12%, isopropyl
Alcohol 30%, ethanol 31%, surplus are water.
Above-mentioned cleaning agent is used for atomizer, drift tube, light pond and the tail pipe cleaned in evaporation photodetector.
When cleaning agent is water, using flushing plus ultrasonic power measure, at 110 DEG C -115 DEG C, cleaning is done for cleaning temperature control
Only 90min-100min is needed.
When cleaning agent is methanol, using flushing plus ultrasonic power measure, at 65 DEG C -70 DEG C, cleaning is done for cleaning temperature control
Only 50min-60min is needed.
When cleaning agent uses mentioned reagent, and with rinsing plus ultrasonic power determines, cleaning temperature is controlled at 85 DEG C -90 DEG C,
Cleaning up needs 20min-30min.
Shown in table specific as follows：
| Sequence number | Cleaning temperature | Related component | Method of testing | Clean duration | Reduced parameter |
| 1 | 115 DEG C of high temperature | Water | Flushing+ultrasound | 90min | There is residual |
| 2 | 70 DEG C of low temperature | Methanol | Flushing+ultrasound | 60min | There is residual |
| 3 | Medium 90 DEG C | Reagent is configured to rinse | Flushing+ultrasound | 30min | It is basic to remove |
During using the present embodiment, using above cleaning agent each component ratio, cleaning temperature is moderate, greatly shortens cleaning
Used time, reduce the damage to instrument.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
