What the registry confirms, and what stays open.
Detection Limits and Chamber Sizes Published per Model
Each catalogue page gives the element range, detector resolution, detection limits by element, tube voltage and current, chamber and overall dimensions and weight. For a RoHS buyer these are the figures that decide whether an analyzer can screen to the 1,000 ppm (Pb, Hg, Cr(VI), PBB, PBDE) and 100 ppm (Cd) limits of the EU directive with margin: the stated limits of 1–5 ppm are well inside them. The figures are the company’s own and have not been independently tested.
Licensed to Produce XRF Instruments, and to Export
The registry read (2026-09-22, official source) records the scope in its own words as including 许可经营项目：能量色散X荧光光谱仪、分析仪器、光学仪器的生产 — production of energy-dispersive X-ray fluorescence spectrometers, analytical and optical instruments as a licensed activity — alongside their research, development and sale, embedded software, and 货物及技术进出口 (import and export of goods and technology). The registered industry classification is wholesale.
An X-Ray Instrument: Radiation Documents Matter
Every EDXRF and coating gauge on this page contains an X-ray tube. In China, producing and selling ray apparatus requires a radiation-safety licence; importing markets have their own rules (in the United States, analytical X-ray equipment is a radiation-emitting electronic product reported to the FDA). The catalogue describes full-path shielding, a triple safety design and hardware and software interlocks, but no licence or dose-rate test report was included in the material supplied — both are listed below as documents to request.
Registry Tags: High-Tech and Innovative SME
The registry record carries 高新技术企业 (High-Tech Enterprise) and 创新型中小企业 (innovative SME) tags. The catalogue refers to Delp patented technology in the X-ray source, excitation structure and positioning system; patent numbers were not given.
Catalogue Claims That Do Not Agree
Two figures conflict within the IDP-7300 page: the text says the SDD detector can cut test time to one second, while the specification lists 60–200 seconds; and resolution is given both as “down to 125 eV” and as 127 eV ±5. The DP-8800 page describes the company as the only domestic maker of vacuum full-spectrum CCD spectrometers and cites European technology, and the LC-1000T page cites German technology; none of those statements has a source. They are reproduced as the company’s claims, not confirmed.
Registry Risk Record
Current self-risk items are three: a hearing announcement mentioning the company, a judgment in a copyright (online-dissemination) case in which the company was the defendant, and a case the company filed. Historical items number fifteen and include four tax-arrears notices, one past court-enforcement record, one past listing for a missed annual report, three case filings, four hearing announcements and two judgments in sales-contract suits the company brought. Advisory items record five investor changes, seven key-personnel changes, one capital change and three address changes. Case numbers are not published here.
What was checked — and what the check found.
The registry read is done: status, scope, capital, insured headcount, registry tags and the risk record come from an official registry source read on 2026-09-22. The catalogue supplied is product pages only: it contains no company profile, no certificate and no test report. For an instrument that contains an X-ray tube, the documents a buyer or importer will ask for first are the maker’s radiation-safety licence, a dose-rate test report for the exact model, and the CE declaration of conformity. The licence image published on the company’s own website expired on 2022-03-08, and the radiation report shown there was commissioned by another company; none of the three has been sighted in current form, and this page will be updated when they are provided.
A registered analytical-instrument maker, read off its registry record and its own catalogue.
Delp Instrument is the trading name of Shenzhen Delp Instrument Co., Ltd. (深圳德谱仪器有限公司), registered on 2011-07-28 in Shenzhen and now based in Shajing, Bao’an district. An official registry read on 2026-09-22 confirms active (存续) status, RMB 5 million of capital paid in full, 23 people on social insurance, and a registered scope that includes licensed production of energy-dispersive X-ray fluorescence spectrometers, analytical and optical instruments, their research, development and sale, and the import and export of goods and technology. The record carries High-Tech Enterprise and innovative-SME tags.
The catalogue supplied covers six instruments: four benchtop EDXRF analyzers for RoHS, halogen-free and heavy-metal screening, an XRF coating thickness and precious-metal gauge, a full-spectrum spark optical emission spectrometer and a gradient HPLC. Each page publishes element range, detector resolution, detection limits by element, chamber size and weight — figures a laboratory buyer can compare directly, though none has been independently tested.
Three things are disclosed rather than smoothed over. The registry risk record is heavy for a company of this size: fifteen historical items including four tax-arrears notices and a past enforcement record, and three current items including a copyright judgment against the company. Two figures on one catalogue page disagree, and claims of European and German technology have no source. And for instruments that contain an X-ray tube, no radiation-safety licence, dose-rate report or CE declaration was included in the material supplied.
Registered in Shenzhen in 2011, licensed to produce XRF instruments.

Frequently Asked Questions
What does Delp Instrument make?
Benchtop energy-dispersive X-ray fluorescence analyzers for RoHS, halogen-free and heavy-metal screening (DX-320, DX-320L, DX-520L, IDP-7300), an XRF coating thickness and precious-metal gauge (IDP-6300), a full-spectrum spark optical emission spectrometer for metals (DP-8800) and a gradient HPLC (LC-1000T).
Can an XRF analyzer test all ten EU RoHS substances?
No. XRF measures elements, so it screens lead, mercury, cadmium, total chromium and total bromine, which stand in for the four metals and the two brominated flame retardants. Hexavalent chromium, PBB and PBDE need confirmatory wet-chemistry or chromatographic methods, and the four phthalates added in 2015 need chromatography. XRF is the screening step in the IEC 62321 series, not the whole test.
Is this listing CMH-verified?
Yes, on the registry check: an official registry read on 2026-09-22 confirms active status since 2011 and a scope that includes licensed production of X-ray fluorescence and analytical instruments and the import and export of goods. That covers the registry facts. It does not cover the radiation-safety licence, certificates or performance figures, none of which has been sighted or independently tested.
What documents should an importer ask for?
For the X-ray instruments: the maker’s radiation-safety licence, a dose-rate test report for the exact model, the CE declaration of conformity for the EU, and, for the United States, the FDA accession number from the abbreviated report filed for analytical X-ray equipment. In China, producing and selling these X-ray instruments requires a radiation-safety licence from the provincial environment authority, unless the model holds an exemption filing. For all instruments: the calibration standards and certificates supplied with the unit, and the warranty on the X-ray tube and detector.
Is there a court or tax record for this company?
Yes. Current items are three: a hearing announcement, a copyright judgment in which the company was the defendant, and a case the company filed. Historical items include four tax-arrears notices, one past enforcement record and one past listing for a missed annual report, together with case filings, hearings and sales-contract judgments. Advisory items show frequent investor and personnel changes.
What is not confirmed yet?
MOQ, lead time, warranty and export markets are not stated. No certificate, licence or test report was included. Two figures on the IDP-7300 page disagree, and the statements about European and German technology and being the only domestic maker of vacuum CCD spectrometers have no source.
Talk to Delp Instrument directly.
Send the material you need to screen (plastics, alloys, plating, solder, jewellery), the elements and limits your customers specify, and the destination country. Ask for the detector type of the exact model, the radiation dose-rate test report at the cabinet surface, the CE declaration and the radiation-safety licence, and the calibration standards shipped with the unit. None of those is confirmed on this page.
