[Spark Table]

· Full digital solid-state spark source with adjustable spark power and frequency can be used to analyze different kinds of materials.

·The particular design of spark table with constant temperature and ringed airflow insure the stability of the instrument with continuous sparks.  This design is better than water cooling.

·Safeguard prevents the instrument from unsafe spark.

·Spark table with cupreous base is easy to be disassembled and cleared.

·Samples with multifarious shape such as cake- shaped ,club-shaped and line-shaped can be analyzed with using of particular fittings.

·The integrative valve with lens avoids the pollution of the optical chamber which brings on intensity fall. And the lens is easy to be replaced.

·The particular design of discharging chamber makes the best condition for discharge.
