用OLGA技术研究了第5族元素Nb、Ta和Db在溴化气氛中的等温气相色谱行为。发现Db形成非常挥发性的化合物，最有可能是五溴化物，比在相同条件下分别与Nb和Ta形成的类似化合物更易挥发。这一观察结果与以前对同一化合物的实验研究不一致，但与理论预测一致。
The isothermal gas chromatographic behaviour of the group 5 elements Nb, Ta and Db was investigated in a brominating atmosphere using the OLGA technique. It was found that Db forms a very volatile compound, most likely the pentabromide, being more volatile than similar compounds formed under identical conditions with Nb and Ta, respectively. This observation is in disagreement with previous experimental investigations of the same compound but in agreement with theoretical prediction.
