When you are choosing spectroscopy analysis detection equipment, the first decision isn't brand loyalty. It's the measurement job. The GE Sievers TOC 900 LAB Portable TOC Analyzer is a portable total organic carbon analyzer, while the BYK 6320 Acquire Rx Multiangle Spectrometer is built for auto paint color matching. These two tools serve different parts of the analysis workflow, and their listed prices, conditions, and intended uses point in very different directions.
Quick Verdict
If your primary task is measuring total organic carbon, the GE Sievers TOC 900 LAB is the one that matches that application. If you need automotive paint color matching, the BYK 6320 Acquire Rx is the practical alternative. The GE is listed at USD 999.99; the BYK is listed at USD 220.00. That is a USD 779.99 spread, but the lower number only helps if the BYK's paint-matching function is actually what you need.

Where Each Product Wins
GE Sievers TOC 900 LAB wins if your workflow is carbon analysis. The title identifies it as a TOC analyzer, and the description confirms it was tested to power on. The obvious limitation is the condition: it is not a plug-and-play lab instrument and needs hands-on attention.
BYK 6320 Acquire Rx wins if you need to match automotive paint colors. As a spectrometer, it is designed to read color from different viewing angles, which is a common requirement in paint matching. That makes it the more specific tool for color work and less of a general analyzer.
Product Notes
GE Sievers TOC 900 LAB
The GE Sievers TOC 900 LAB is a portable total organic carbon analyzer, so it belongs in a different conversation than a paint spectrometer. If your lab runs TOC tests, this unit's model and MPN identify it as a Sievers TOC 900 LAB. One concrete reason to choose it is that it is tested to power on, which gives you a starting point even though the unit is sold as-is. The main limitation is the stated condition: 'For parts or not working.' That means you should expect to troubleshoot or repair before relying on it. The included power cable is a useful part of the package, but the instrument itself needs hands-on attention.
BYK 6320 Acquire Rx
The BYK 6320 Acquire Rx is a multiangle spectrometer aimed at auto paint color matching. If your work involves reading color at multiple angles to match a repair finish, this tool addresses that need directly. The product is identified with model BYK 6320 Acquire Rx and MPN 6320, so you have concrete identifiers for the unit. One reason to pick it is that it is listed as used rather than for parts, so there is no repair-project warning attached to it. The limitation is that this is a used test instrument, so you are not getting a new unit. If your job is paint matching, the BYK's angle-based reading capability is the specific feature to look for.
Final Choice by Use Case
Choose the GE Sievers TOC 900 LAB when your application is total organic carbon analysis and you are willing to take on a portable analyzer that needs attention. The power-on test helps, but the expectation should be repair or refurbishment.
Choose the BYK 6320 Acquire Rx when your application is automotive paint color matching and you want a spectrometer aimed at color measurement. It is aimed squarely at color measurement rather than carbon analysis.
If you need broad spectroscopy analysis detection coverage, make sure the instrument matches the measurement you actually run. The GE is the TOC analyzer in this pair; the BYK is the paint-matching spectrometer. Match the instrument to the measurement, not the other way around.
