US "Emerald" Class-Action Lawsuit Sparks Food Safety Fears: AnYiPu's TQ & Electrostatic Trap Dual Platform Delivers One-Stop Solution to Food Testing Challenges

Suzhou AnYiPu Precision Instruments, a leading domestic manufacturer of high-end mass spectrometry systems, leverages its complete domestic mass spectrometry portfolio—including the TQ8100/8120GC-MS/MS, TQ 9100/9120LC-MS/MS, and China-exclusive GC Cassitrap, LC Cassitrap 120K quadrupole-Fourier transform ion cyclotron resonance (FT-ICR) ultra-high-resolution mass spectrometer—to deliver an integrated food testing solution combining batch quantification with high-resolution confirmation. This approach simultaneously addresses three critical industry challenges: routine pesticide residue compliance, PFAS trace screening, and precise differentiation between true and false positives, establishing a robust domestic technological foundation for end-to-end food safety across the fruit and vegetable supply chain in China.

The recent "Blueberry" incident exposes two critical gaps in the food testing industry: First, GB 23200.121-2026 expands plant-based pesticide screening to 352 compounds, with some limits of quantification as low as 0.002mg/kg. Legacy low-end mass spectrometers lack the sensitivity required for legally binding reports. Second, PFAS compounds have unique polarity and strong matrix interference from berries. Traditional low-resolution mass spectrometry frequently yields false positives or negatives and cannot detect novel fluorinated pesticides or metabolites outside national standards, creating significant safety blind spots. Historically, high-end mass spectrometry equipment has relied heavily on imports, resulting in prohibitive procurement and maintenance costs. Domestic laboratories currently lack a complete domestic solution that balances routine high-volume testing with risk tracing for unknown contaminants.

To address dual regulatory compliance pressures in the industry, AnYiPu has launched a tiered, end-to-end testing platform. It delivers full coverage of GC-MS/MS and LC-MS/MS analysis, establishing a closed-loop capability for routine batch screening, trace PFAS quantification, and high-resolution arbitration of unknown contaminants.

1. TQ8100/8120 GC-MS/MS and TQ9100/TQ9120 LC-MS/MS have completed full national standard method validation, meeting routine batch compliance testing requirements.

An益谱 TQ8100/8120 Triple Quadrupole GC-MS/MS has completed full method validation per GB 23200.113 standard. Using universal QuEChERS sample preparation, it fully supports 242 gas chromatography-stable pesticide residue testing requirements.

Paired with the TQ9100/TQ9120 ultra-high-performance liquid chromatography triple quadrupole mass spectrometry platform, it fully complies with the updated GB 23200.121 national standard for detecting 352 pesticide residues. It performs hundreds of pesticides simultaneously via DMRM scanning in just 30 minutes per sample across diverse matrices, with quantification limits meeting all national requirements. The system also features a dedicated PFAS detection suite integrated with online solid-phase extraction (SPE), enabling simultaneous analysis of over 30 long- and short-chain perfluoroalkyl substances. This solution is optimized for trace PFAS detection in high-pigment berries like strawberries, effectively overcoming technical challenges such as poor retention of short-chain PFAS and matrix ion suppression. Equipped with intelligent analysis software, it includes a built-in database of thousands of national pesticide residue limits, automatically flags samples exceeding thresholds, and generates legally compliant reports with one click—ideal for high-volume enterprise self-testing and third-party routine sampling.

II. GC/LC Cassitrap 120K Domestic High-Resolution Mass Spectrometer Launches: Overcoming False Positives/Negatives and Unknown Compound Screening Bottlenecks

AnYiPu launched its self-developed GC Cassitrap and LC Cassitrap 120K ultra-high-resolution quadrupole-Fourier ion trap mass spectrometers in 4 of 2024 and 6 of 2026, respectively. This breakthrough ended the long-standing monopoly by imported Orbitraps and magnetic sector instruments, establishing a unique technical barrier in risk assessment for fruits, vegetables, and agricultural products.

This platform features a dual-stage analysis architecture combining quadrupole pre-screening with ultra-high-resolution electrostatic ion traps, delivering stable mass accuracy ≤2 ppm. It precisely distinguishes matrix interferences, pesticide isomers, and PFAS homologs (long- and short-chain), eliminating false positives and negatives common in low-resolution MS. Results are legally defensible for arbitration and forensic tracing. The system also supports untargeted full-spectrum screening without predefined target ions. Coupled with an in-house library of 1,000+ dedicated high-resolution entries for pesticides and PFAS, it verifies all national standard pesticide residues while flagging emerging fluorinated pesticides and degradation pollutants not yet covered by standards—perfectly addressing global regulatory trends of expanding PFAS scopes and annually updated residue limits.

Dual high-resolution platform with complementary roles: LC Cassitrap targets polar pesticide residues and trace qualitative analysis of the full PFAS spectrum; GC Cassitrap covers volatile pesticides and semi-volatile fluorinated additives. Together, they enable comprehensive risk screening for fruits and vegetables—from water-soluble and volatile residues to short- and long-chain PFAS and unknown fluorinated pollutants. This integrated solution is a core differentiator for export-oriented produce companies, provincial regulatory labs, and premium third-party testing facilities.

Fully domestic core hardware and algorithmic software. Compared to imported high-end equipment, procurement costs are reduced by 40%. With a localized technical service team, we deliver complete high-resolution methods for pesticide residues and PFAS simultaneously, significantly lowering the barrier to deploying high-resolution equipment in laboratories.

3. Three-tier configuration plan covers all industry user needs, comprehensively supporting food safety control.
Leveraging our complete mass spectrometry product portfolio, AYS provides tiered deployment solutions tailored to laboratories of all sizes:

1. Basic configuration for fruit and vegetable production enterprises: TQ9100/9120 LC-MS/MS. Completes screening of 352 pesticide residues plus routine PFAS at the factory gate to meet basic compliance self-check requirements.

2. Small and medium-sized third-party testing laboratories: TQ8100/8120 GC-MS/MS + TQ9100/9120 LC-MS/MS triple quadrupole combination. Fully covers all national standard pesticide residues and targeted PFAS testing, supporting CMA accreditation expansion and high-volume sample submissions.

3. Head detection, export enterprises, and market regulation labs: the ultimate solution featuring QQQ dual-platform + GC/LC Cassitrap 120K dual high-resolution mass spectrometry. This delivers integrated capabilities for batch quantification, unknown screening, and positive confirmation—meeting stringent EU/US import/export standards and enabling rapid traceability during food safety incidents.

The recent "problematic strawberry" incident clearly demonstrates that the trust logic in the food industry has fundamentally shifted. Self-test reports from companies alone no longer gain market or consumer acceptance. Only authoritative, comprehensive, auditable, and traceable test data can rebuild brand credibility. Anypu's full-spectrum domestic mass spectrometry solution balances high-volume routine testing with early warning for emerging contaminants. Leveraging autonomous, high-end instrumentation, it helps Chinese agricultural enterprises, testing agencies, and regulatory bodies simultaneously address both new national standards and global PFAS regulations—reducing reliance on imported equipment.
