LAS-1000 Liquid Autosampler

LAS-1000 Liquid Sample System
LAS-1000 Liquid Autosampler

ATOM Instrument offers the necessary tools and accessories to meet the growing needs and challenging demands of the analytical world. The ATOM LAS-1000 Liquid Autosampler is built for ultra-fast, reliable, efficient and safe handling of liquid samples with seamless integration to the ATOM XT Series laboratory Total Sulfur/Total Nitrogen analyzer. The autosampler does not require any additional benchtop space for operations with the XT Series analyzers. The LAS-1000 combined with the XT series analyzers provides unmatched analytical performance making it suitable for a wide variety of applications and industries.

  • Meets ASTM D5453 and D4629 Requirements
  • Accurate and Precise Sample Handling
  • XYZ-axis Vectorized Movement
  • Fully Servo-motor Controlled
  • Full Integration with XT Series Software
  • Safe Operations
  • No Additional Benchtop Space Required
  • Large Sample capacity: 162 Vials of 2 mL per tray holder with up to 2 trays holders
  • Syringe Protection with Missing Vial Detection
  • Optimized Movement for highest sample analysis rate
  • Highly Reproducible Injection
  • Faster Analysis for higher throughput

Enhanced Features

The LAS-1000 is mounted directly on top of the XT analyzer eliminating the need for additional benchtop space. The use of servo-motors allows rapid, precise and accurate control of movements and eliminates routine maintenance needs. The use of XYZ-axis vectorized movement for sample handling reduces the time needed for operations.

Outstanding Repeatability

The LAS-1000, combined with the XT Series Analyzers, ensures optimal analytical performance. Autosampler injection repeatability below 0.60% RSD and linearity R>0.9999 allow the LAS-1000 combined with the XT Series analyzers to achieve 30 ppb repeatability for both Total Sulfur and Total Nitrogen Measurement.

Easy To Use

The LAS-1000 operation is fully integrated with the XT Series and managed directly through the Laboratory User Interface (LUI). The LUI software allows configuration and operation of the autosampler movements while giving users full control over the various analysis options.

Outstanding Analytical Performance

The table below displays results of a 6.0 ppm/wt. Ultra Low Sulfur Diesel (ULSD) sample acquired with an XTS-1000 combined with the LAS-1000. The 10 run-graph above showcases the analytical performance and high speed of analysis of the XTS-1000/LAS-1000 system.
