Transformer oil furfural testing method with chromatography pump support
A transformer oil method targeted furfural as an aging indicator for transformer paper insulation, using the DL/T 984-2018 reference and chromatography pump support to build a practical industrial testing workflow.
Background
Requirement context
The China site explains that furfural in transformer oil is associated with paper insulation aging. This creates a useful industrial application page beyond food, pharmaceutical, and environmental testing.
Selection challenges
What needed confirmation
Connect the industrial sample matrix to a chromatography method rather than a general instrument inquiry.
Confirm pump performance, detector selection, column conditions, and sample preparation requirements.
Document the reference method and aging-indicator purpose for technical review.
Workflow architecture
From requirement to quotation
Instruments
High-pressure pump, HPLC system, detector, column, and workstation by final method selection.
Confirmation Layer
Transformer oil sample, furfural target, reference method, flow requirements, and documentation.
RFQ Review
Industrial chromatography RFQ for transformer oil aging-indicator testing.
Configuration path
Application stages
Flow delivery
LC-500Q high pressure infusion pump or HPLC pump module
Provide stable flow for transformer oil furfural method conditions.
Chromatography analysis
HPLC separation, detector, column, and workstation by final method
Measure furfural as an indicator related to transformer paper insulation aging.
Result
RFQ output and buyer value
Reference method
DL/T 984-2018 was listed as the reference.
Industrial buyers can start from a recognized power-industry method.
Application value
Furfural content is used to evaluate transformer paper insulation aging.
The case links chromatography equipment to a clear maintenance and risk-control purpose.
The case expands Tianzhao's application coverage into power equipment oil testing.
It gives LC pump and HPLC modules a method-based use case.
The RFQ should request sample matrix, method reference, pump requirements, detector, column, and documents.
