Dutch term or phrase: ...worden ... Brønsted zuren BH+
My text is about mass spectrometry, here specifically chemical ionization. I'm not sure how to interpret the highlighted section.

In deze ionisatiemethode vindt vorming van ionen uit te onderzoeken verbindingen plaats door middel van ion/molecuul reacties. In tegenstelling tot de EI methode wordt nu bij een druk van ongeveer 10 - 20 Pa in de ionisatiekamer gewerkt. Deze druk wordt opgebouwd met behulp van reactant gas. De gasmoleculen worden beschoten met elektronen met een kinetische energie van 200 - 300 eV. Dit leidt tot de vorming van reactant gas radicaal kationen. Bij hoge druk in de ionenbron **worden vervolgens door ion/molecuul reacties Brønsted zuren BH+**. Deze BH+ ionen reageren in de gasfase primair door een proton overdracht naar moleculen die een hogere affiniteit hebben voor het proton dan de geconjugeerde base B.

Is the text incomplete so that it reads as 'Under high pressure conditions in the ion source, Brønsted acids (BH+) are formed as a result of ion-molecule reactions.'

Or do Brønsted acids 'become' BH+ - i.e. 'Under high pressure conditions in the ion source, Brønsted acids ionize to BH+ as a result of ion-molecule reactions.'

... form... Brønsted acids BH+
Explanation:
'In Eq(10) the Brønsted base B accepts a proton H+ from the Brønsted base H2O to form the conjugate acid BH+ and OH–'

As you already suggested, the sentence seems incomplete. I agree that the translation should be: 'Under high pressure conditions ....Brønsted acids (BH+) are formed as a result of ion-molecule reactions.'
