The March 15 gala in 2025 exposed the chaos in many fields such as food, daily necessities, and building materials. Among them, shrimp phosphate exceeded the standard, refurbished sanitary napkins/diapers, false sterilization of disposable underwear, and non-standard wires and cables attracted widespread attention. Scientific instruments, as the "guardians of the truth", are the key tools to crack these chaos. As an enterprise deeply involved in the field of analytical instruments, East-West Analysis has always been committed to helping the industry improve detection accuracy and transparency and protect consumer rights and interests through core technologies such as chromatography, mass spectrometry, and spectroscopy. The following is a combination of the 315 exposure incident to analyze the application scenarios of instrument technology in consumer safety.
Phosphate excess shrimp
The amount of shrimp water-retaining agent (phosphate) exposed at the party exceeded the standard by 145%. The merchant soaked the shrimp by adding complex phosphate (such as sodium tripolyphosphate) in excess, and the water retention rate could reach 20% -30%. Even with the ice-wrapping process, "0.5 kg shrimp 7 taels of ice" was achieved. Long-term intake of excessive phosphate led to an imbalance in calcium and phosphorus metabolism, which increased the risk of kidney stones, osteoporosis and cardiovascular diseases. If it is co-polluted with heavy metals (lead, cadmium), the harm will be superimposed.

Ion chromatography (IC): Quickly determine the phosphate concentration in shrimp, and accurately determine whether it exceeds the national standard limit (GB 2760-2024 stipulates the phosphate addition amount of 5g/kg). East-West Analysis IC-2800 Ion Chromatograph adopts SH-AC-4 anion exchange column chromatography column and layer leaching technology, which can realize the simultaneous separation of 4 phosphates (detection limit is as low as 0.05mg/kg)
IC-2800 ion chromatograph
Inductively coupled plasma spectroscopy (ICP-OES): Simultaneous detection of heavy metals (such as lead and cadmium) residues to ensure the safety of raw materials.

Refurbished diapers
The 315 party exposed the black industry chain of refurbished sanitary napkins/diapers. The defective products are sold for the second time under the name of "second-class products" after simple sorting, and the profit margin exceeds 400%. Some of the defective materials are crushed and processed into industrial waste, which flows into the market again. Lead, mercury and arsenic in recycled materials exceed the standard, causing blood toxicity through skin penetration. Illegal additives such as photowhitening agents (VBL), formaldehyde and phthalates directly contact the skin, causing allergies, gynecological inflammation and even carcinogenic risks.

Atomic Absorption Spectrophotometer: Heavy metals such as lead (Pb) and mercury (Hg) are mixed into the production waste of refurbished diapers, which can cause blood toxicity through skin penetration. The AA-7050 atomic absorption spectrophotometer can complete the screening of 8 heavy metals such as lead and mercury.

Non-standard wire and cable
The chaos of non-standard wires and cables exposed at the CCTV 315 party in 2025: from cutting corners at the production end of "copper core adulteration (99% purity), the use of bromine-containing waste plastics in the insulation layer (bromine content exceeding 23 times the standard) ", to the "certification fraud" of falsifying test reports at the circulation end, the one-stop counterfeiting and selling of shoddy cables has turned cables that should be safe into "invisible bombs" - the inferior copper core doped with aluminum and iron causes resistance to soar and the risk of short-circuit fire to increase sharply; the burning of bromine-containing waste plastics releases highly toxic gases such as dioxin; the cutting corners process makes the cable pressure resistance drop off a cliff. These non-standard cables hidden in buildings and homes are eroding the public safety line under the guise of "low price", and each one may become a fuse to ignite tragedy!
East-West Analytics Solutions
ICP-7760HP full-spectrum direct reading inductively coupled plasma emission spectrometer: It can accurately determine the content of copper and aluminum in inferior copper core cables.
ICP-7760HP Full Spectrum Direct Reading Inductively Coupled Plasma Emission Spectrometer
Gas chromatography-mass spectrometry instrument: Inferior cables use bromine-containing waste plastics as insulation layers, which release highly toxic gases such as dioxin in case of fire. GC-MS3250 gas chromatography-mass spectrometry instrument can accurately identify the characteristic peaks of brominated flame retardants such as decabromodiphenyl ether in bromine-containing waste plastics with its high-precision analysis ability.

In the battlefield of consumer trust crisis, scientific instruments are the sword to pierce lies and the cornerstone to rebuild confidence. East-West analysis will continue to focus on chromatography, mass spectrometry, and spectroscopy technologies to provide the industry with a full-chain solution of "detection-traceability-rectification". Let data become the scale of integrity, and let technology illuminate the future of consumption.
