PAL-xt Systems

Product catalog summary
Overview: The document provides detailed specifications and test procedures for the PAL-xt System, focusing on various chromatographic tests and syringe volume specifications.
Specifications:
  • Syringe Volume Specifications: Different syringe volumes (10 µL, 100 µL, 1000 µL, 2500 µL) are tested for repeatability and linearity. The relative standard deviation (s-rel) and correlation coefficients are specified for each volume.
  • Gravimetric Test: Specifies repeatability with a relative standard deviation of 0.30% and notes that carry-over is not applicable.
  • Gas Chromatographic Tests: Includes tests for high split ratio, split mode, and headspace with specific conditions such as split ratios, column types, and detector settings.
  • HPLC Chromatographic Tests: Covers loop overfill and partial loop filling techniques with detailed syringe settings and test conditions.
Test Procedures:
  • Gravimetric Test: Involves transferring water into target vials and measuring repeatability.
  • Gas Chromatographic Tests: Conducted using iso-Octane as a solvent with specific injector and detector settings.
  • HPLC Tests: Include loop overfill and partial loop filling with different sample volumes and solvents.
General Remarks:
  • Temperature and barometric pressure are not considered in tests.
  • Repeatability is determined, but not accuracy.
  • Specific equipment and software versions are used for data acquisition.
Formulas: The document includes formulas for calculating mean values, standard deviation, and relative standard deviation for injection precision and repeatability.
