摘要： A novel approach to sample deposition in furnace atomization is disclosed which obviates the need for skilled application of microvolumes by syringe. By means of the apparatus and method disclosed, the analyte in aerosol form is deposited under controlled conditions on the internal surface areas of graphite furnaces. Precision approaching that of flame atomization systems is achieved and at the same time, concentrational sensitivity may be increased simply by extending the deposition time. The amount of analyte deposited in the furnace is restricted only by the sample volume available and the matrix concentration. A single standard can be used to construct a calibration curve by simply varying the aerosol deposition time.
摘要翻译：公开了一种在炉子雾化中样品沉积的新方法，其消除了通过注射器熟练应用微量体积的需要。通过所公开的装置和方法，将烟雾形式的分析物在受控条件下沉积在石墨炉的内表面区域上。实现了火焰雾化系统的精确逼近，同时可以简单地通过延长沉积时间来增加浓度灵敏度。沉积在炉中的分析物的量仅由可用的样品体积和基质浓度限制。单一标准可用于通过简单地改变气溶胶沉积时间来构建校准曲线。

摘要： Apparatus for directly controlling the power delivered to an electrically heated furnace atomizer for use in atomic spectroscopy and thus for controlling the temperature of the furnace by utilizing dimensional changes produced in the furnace due to thermal expansion and contraction to produce electrical signals that are used by means of a feedback control to control the electrical input to the furnace.
