Zhongxi is a complete laboratory for analysis and testing, also an audited contract laboratory.We can provide a wide range of chemical analysis and material testing services to a diverse international customer base.Our expertise and years of experience enable us to choose the right analytical methods and generate the accurate data needed to solve your toughest problems.

Zhongxi has over 21 years of experience in Product Analysis and Complete Product Deformulation. The goal of this type of testing is usually to produce a complete list of ingredients along with their percentages in the formulation. This report should provide the client with enough information to recreate the product or further modify the product to prepare a product suitable for the needs of the client.

Our analytical testing laboratory customizes its testing methods based on the specific needs of our clients and our scientists remain up-to-date with the most sophisticated analytical instrumentation, testing methods, and problem-solving techniques.

Zhongxi offers a range of custom chemical testing, material analysis & Id., professional analytical testing services, and custom formulation development services.


·Define and solve manufacturing problems

·Recommend and implement specific testing methods and research protocols

·Provide high-quality results and analysis

·Investigate product/process development with your staff

·Identify any mission-critical support

·Maintain internal support facilities

Sample Preservation

In certain situations, non-destructive testing services are needed when a material is being used in litigation, or additional samples are not available and the sample is still required.

Some laboratory tests remove or destroy a small amount of a sample during the testing process in order to break down and analyze it. This can be due to the size of a sample, type of sample, or what kind of analysis can be performed. Zhongxi has a wide range of testing instruments and techniques available, which allow our scientists to be able to perform non-destructive testing and analysis when needed. This type of testing is not always preferred unless necessary as it limits which instruments can be used, and can affect both how detailed an analysis can get, as well as costs for testing.

Partial testing instrument

·Fourier Transform Infrared Spectrometer

··Nuclear magnetic resonance (NMR)

·Time of flight mass spectrometer

·Gas Chromatography-Mass Spectrometer

··Inductively Coupled Plasma Optical Emission Spectrometer

·Thermo gravimetric Analysis

·RAMAN Spectroscopy

·Scanning Electron Microscopy (SEM)

·Energy Dispersive X-Ray Spectroscopy (EDS)

·X-Ray Diffraction (XRD)

·Transmission Electron Microscopy (TEM)

·Atomic Force Microscopy (AFM)

A minimal amount of the sample may be consumed, but the majority will be preserved. Sample preservation testing is ideal for analyses with minimal amounts of sample available for testing.

If you have a limited sample that you cannot have harmed or destroyed or a sample that is involved in litigation, Zhongxi’s scientists can come up with a way to complete analysis while leaving the sample intact.
