为鉴定进出口商申报名称和实际货物是否相符,或确定商品的品名,而需要科学、准确、及时、公正的检测。海关化验中心成立十余年了,在这十余年里,海关和能谱科技公司建立起了长期的合作。通过长期的使用,我们认为傅立叶红外光谱仪有下列优点:

1.任何气态、液态、固态样品均可进行红外光谱测定。这是核磁、质谱、紫外等方法所不及的。 

2. MEIZHONGHUAHEWUJUNYOUHONGWAIXISHOU,YOUYOUJIHUAHEWUDEHONGWAIGUANGPUKEDEDAOFENGFUDEXINXI。YIBANYOUJIWUDEHONGWAIGUANGPUZHISHAOYOUSHIJIGEXISHOUFENG。GUANNENGTUANQUDEXISHOUXIANSHILEHUAHEWUZHONGCUNZAIDEGUANNENGTUAN,ERZHIWENQUDEXISHOUZEDUIHUAHEWUJIEGOUJIANDINGTIGONGLEKEKAODEYIJU。

 

3.常规红外光谱仪上海11选5走势图价格低廉(与核磁、质谱相比),易于购置。

4.YANGPINYONGLIANGSHAO。

5.针对特殊样品的测试要求,发展了多种测量技术,如衰减反射光谱(ATR),漫反射,红外显微镜等。由于由如上的优点,所以傅立叶红外光谱仪在海关化验领域有非常广泛的应用。我们中心根据傅立叶红外光谱仪的产品特性,开发了很多快速、有效和适合海关工作特点的方法。
