PG-Spark Detailed Product Description

Product Description

The PG SPARK OES Metal Analyser is widely used for chemical composition analysis of Irons and Steels, Aluminum, Copper, Nickel, Cobalt, Magnesium, Titanium, Zinc, Lead, Tin, Silver and other metals and alloys.

PG Spark CCD Optical Emission Spectrometer uses a high-resolution linear CCD to perform full-spectrum scanning from 130-900nm. The PG Spark also benefits from an intelligent argon controlled flushed spectrometer chamber system thus ensuring maximum stability for long periods of analysis and the use of analytical wavelengths unconstrained. This includes analysis for elements such as Carbon, Nitrogen, Sulphur, Arsenic, Boron and Phosphorus at ultra-low levels.

Key Applications

  • Large Steel Plants where needs are at about 10ppm for elements such as C, N, Cr, S, P
  • Pure Metal applications for purity of metals such as Al, Cu, Pb, Zn, Mg, Ti etc.
  • Testing Laboratories, Commercial testing Labs, Small Foundries etc.
  • Regulatory compliance for very low limits of detection such as Pb, As, Cd.
  • Foundries which need a fast, accurate and precise analysis from materials in the production furnaces.
  • Analysis of non ferrous alloys such as Aluminium. Copper, Lead, Tin, Titanium, Silver etc.
  • Warehouse material identification
  • Manufacturing facilities.

Programmable Control Argon-Flushes Spectrometer Chamber

  • The Spectrometer Optical Chamber is a NEW optical chamber with an extremely low thermal expansion coefficient which provides high instrument stability.
  • The argon flush to the Spectrometer chamber is programmed and controlled via the software.
  • The warm-up time for a ‘cold’ machine which has been shut down for 12 hours or more is ONLY 30 minutes. For a system in operation the start time is 5 minutes or less.

 Argon Consumption

  • Argon Flow Rate during analysis is under 8 litres/minute
  • Argon Flow during standby is 60ml/min
  • The flow, pressure and the rate of flow are all programmed via the software

 CCD Detector

  • High Resolution CCD Detector
  • 3648 single chip CCD Pixels
  • Single Pixel size of 8µm

Spark Stand

 The spark stand will take a maximum weight of 50Kg of sample. The Spark Stand has been specifically designed coaxial stand with an optimised internal gas circuit which greatly reduces argon consumption. The sample cavity is cleaned by a Self Purging Function
