A kind of heavy metal analysis equipment
Technical field
The present invention relates to heavy metal analysis technical field, more particularly to a kind of heavy metal analysis equipment.
Background technology
As the exploitation of mankind's heavy metal, smelting, processing and business manufacturing activities are increasing, cause many heavy metals such as lead, mercury, cadmium, cobalt into big gas and water, soil, cause serious environmental pollution.Heavy metal can pass through the path of diet, breathing or directly contact and enter human body, but heavy metal can be then discharged out external unlike other toxin in liver catabolism.Relative, it easily accumulates in brain, kidney and other organs, gradual damage body normal function.Health and development especially to children produces the impact of very severe.Bulk deposition of the toxic heavy metal in tissue and brain can cause and be difficult to avoid contact to heavy metal in the life of serious maldevelopment and nerve damage modern; quickly and accurately verify the content of beary metal that human body is contained within; for heavy metal poisoning is treated in time, especially the healthy of small children patient has great meaning to protection patient.
The common method of heavy metal analysis has the detection and analysis technology such as atomic absorption spectrography (AAS), inductively coupled plasma emission spectrography, and these detection methods are complicated to the pretreatment process of sample and the time is long, it is impossible to realize the demand of real-time live quick detection.Meanwhile, laser instrument used by current spectroscopic methodology detection heavy metal is nanosecond laser instrument, and equipment build is huge, cost intensive.A kind of heavy metal analysis equipment disclosed by the invention, using the laser pulse of distinct pulse widths as light source, excites the atom spectrum of sample to be tested, with reference to synchronous control technique and spectral analysis technique, you can obtain contained heavy metal information in sample object body immediately.Reduce cost, it is to avoid complicated sample pre-treatment procedure, save resources are quick to obtain more accurately testing result.
The content of the invention
Deficiency in order to make up existing heavy metal analysis testing techniques of equipment of the invention, discloses a kind of heavy metal analysis equipment, and by the laser pulse of distinct pulse widths sample atom spectrum is excited, you can obtain contained heavy metal information in sample object body immediately.Reduce cost, it is to avoid complicated sample pre-treatment procedure, save resources are quick to obtain more accurately testing result.
