求翻译：ROHS认证分为两种，一种为整合，基于组装元器件供应商都有ROHS认证，对于样品整体进行检测，这种费用较低；另一种是扫描，对于样品所有组成部分进行检测，比较细致、全面，费用较高，不知道你选那一种是什么意思？

ROHS certification is divided into two, one for integration, based on Assembly components suppliers are ROHS certification, testing the sample as a whole, lower costs for this; the other is scanning, for all components of the sample to be detected, more detailed, comprehensive, high cost, does not know which one to choose
