Nuclear Magnetic Resource Spectrometer

Instrument Model: AVANCE 400

Manufacturer: Bruker Company,Switzerland

Purchase date: June,2003

Main Specifications:

1. Magnet: 400MHz

2. cavity diameter (mm): 54

3. Magnetic field strength: 9.40 Tesla

4. Magnetic field drift: <4Hz

5. Liquid helium retention time: 360 days

6. Probe (5mm): Broadband Viewing Probe (BBO), Broadband Multicore Counter Probe (BBI)

Uses:The instrument can perform one-dimensional, two-dimensional and two-dimensional gradient field experiments (such as hydrogen spectrum, carbon spectrum, DEPT, NOESY, TOCSY, COSY, HSQC, HMQC, HMBC, gCOSY, gHSQC, gHMQC, gHMBC, etc.). It is an indispensable and important means for studying the structure of organic compounds. It is widely used in the analysis of organic structures in the fields of molecular biology, medicine, pharmacy, natural organic chemistry, synthetic organic chemistry, environmental protection, spices, and pesticides, especially in medicine and pharmaceutical intermediates. The analysis of the components of natural products, such as Chinese herbal medicine, etc., is the most widely used, and it has the irreplaceable role of other instruments.
