 Introduction of Analysis & Testing Equipment
 Instrumental Analysis Equipment: 02-08--Glow discharge mass analyzer (Gd-MS)--

VG-9000 VG-9000
Exterior View (V.G. Scientific VG-9000)
 Principle Generates glow discharge in argon gas, and ionizes argon gas.
Ar+ is collided against the analysis sample, ions to be measured are generated from the sample, and the number of ions are measured with a mass spectrograph.
 Usage (1) Analysis of trace element in metals
(2) Multiple elements can be analyzed
(3) Assurance of high-purity metal
(4) Assurance analysis of compositions for aircraft materials
