Testing laboratory was set up in April 2003. Up to the present, our company's laboratories have received cGMP qualification certification. And, most important, our company is the only present domestic company that has passed domestic health governing organizations (Drug Testing Bureau and Chinese medicine Committee, Department of Health and) testing certification. We are the only company that can test both western and Chinese medicines.

• On January 11, 2005, we received approval from Practical Drug Testing bureau, Department of Health to carry out contract testing for western medicine quality control business.

HPLC

Principle: Adsorbent (fixed phase) surfaces have different absorption capabilities against the molecules of different components in a sample, it is used to separate mixed samples for analysis.

FT-IR spectrometer

Principle: It is the method that studies the absorption properties of molecules toward infrared radiation and then utilizes the results to determine the compounds and carry out quantification analysis. The absorbed spectra belong to vibration-rotation spectra.

UV/Vis spectrometer

Principle: This method uses the absorption spectra properties of molecules or ion groups toward UV and visible lights as basis for analysis.

Autotitrator electric potential difference automatic titrator

Principle: Appropriate electrodes is used to track the changes in electric potential. The point with the highest change is used to determine the end point of the titration. Or, the electric potential value that is equivalent to the point of equivalent weight is used to determine the titration end point.

Polarimetric photometer

Principle: Determine substances' polarimetry (levogyration or dextrorotatory)。

Polarimetric photometer

Principle: Utilize vacuum pressure reduction method to carryout concentration of liquid substances.

Coarse fiber analyzer

Principle: test coarse fibers within the five major nutrients.

K-N analyzer

Principle: test coarse proteins within the five major nutrients.

Trace moisture analyzer

Principle: Based on Karl Fischer chemical reaction, this method is the single purpose and most accurate chemical method to determine moisture contents. It can be used to test liquid and solid samples.

Microwave digestion device

Principle: A preprocessing instrument, where microwave is used under high 1400W environment, samples are pressurized to 60bar and 240 ℃ to determine the concentrations of metal elements.

ICP-OES

Principle: After samples are atomized, they are transported by carrying gases to plasma torch. Then, induced coupled plasma is used to heat up and excite the elements to be tested. After excitation, the emitted light spectra are decomposed by light grid into emitting light spectra lines of different specific wavelength. Then, light detector is used to measure the strengths of different light spectra lines.

Dissolution separation analyzer

Principle: Utilizes UV to test samples' absorptivities and determine sample dissolution separation curves to compare against the drugs from the original manufacturers.
