Hi ESdat Online users – we have responded to your requests for being able to include Naphthalene in both the BTEX and PAH suites on reporting tables by introducing a new chem code.

 There is a now a new chem code that is specific to Naphthalene reported as a VOC with the BTEXN suite 91-20-3_VOC. The original Naphthalene chem code of 91-20-3 will continue to be used for Naphthalene when reported as an sVOC.

 The new chem code has already been placed in the BTEX group in the default chem profile, and chemistry results should now be showing up on the one row – but in 2 different groups.

 For historical results – EScIS has automatically applied the new chem code to all Naphthalene results reported in a BTEX or VOC suite.

 If your laboratory results are still showing the Naphthalene results duplicated over 2 rows in your tables – please request your chosen laboratory to use the new chem code.
