After collecting the item in the Bathysphere workshop you will have to take a lift to return to the Service Bay entrance in the hub area.

Upon exiting you'll hear a few splicers talking to each other. If you sneak around the corner you should see 3 enemies clumped together, two sat down one stood up.

Shoot the standing one with the Gas Bolt and you're good!
