Title:
ANALYTICAL SAMPLE PREPARING SYSTEM
Document Type and Number:
Japanese Patent JPH07120364
Kind Code:
A
Abstract:

PURPOSE: To provide a crucible holder to improve hold and control of a melting crucible at operation time of a device to agitate a powder sample and a solvent while they are heated.

CONSTITUTION: A crucible holder 100 is joined to an agitating assembly 200 to provide independently controlled operations on two different shafts by using a separate adjustable variable frequency and amplitude motion running along respective two operation shafts to provide the finite number of agitating patterns for a crucible. A heating flame is controlled by controlling supply of compressed air and combustion gas. In the other suitable shape, a pilot burner 502 is provided. A main burner 300 arranged under the crucible is ignited, and a casting pan is preheated up to the almost same temperature as the crucible. The pilot burner 502 controls air so as to flow by being oriented only to the casting pan to controllably cool a disoluble sample to a form a sample lump.
