Product catalog summary
Overview: This document outlines the specifications and test procedures for various PAL Systems used in gas and liquid chromatography. It includes detailed descriptions of test conditions, equipment specifications, and performance criteria.
1. Gravimetric Test:
  • Focuses on repeatability with a relative standard deviation (s-rel) of 0.30%.
  • Carry-over is not applicable.
  • Test conditions involve iso-Octane in 2 mL vials, using a Hamilton syringe.
2. Gas Chromatographic Tests:
  • High Split Ratio: Uses iso-Octane with a retention gap. Repeatability s-rel is ≤ 0.80%.
  • Split Mode: Utilizes an alkene test mix with a repeatability s-rel of ≤ 1.00%.
  • Headspace Test: Involves iso-Octane with a high split ratio, achieving a repeatability s-rel of < 1.00%.
3. HPLC Chromatographic Test:
  • Tests include loop overfill and partial loop filling with a repeatability s-rel of 0.10% and 0.20% respectively.
  • Linearity is tested across 5 levels with a correlation coefficient R > 0.9999.
4. General Remarks:
  • Repeatability tests involve multiple specimens, with specific conditions for each test.
  • Temperature and barometric pressure are not considered in the tests.
  • Data acquisition is performed using Agilent ChemStation Software.
5. Equipment and Parameters:
  • GC and HPLC systems from Agilent are used, with specific settings for injectors, detectors, and columns.
  • Carrier gases and solvents are specified for each test type.
6. Formulas:
  • Includes formulas for calculating mean values, standard deviation, and relative standard deviation.
