Peter: How do you do?
Mary: How do you do.
Ken: Mary works for ...
A variation is also "It's a pleasure to meet you." or "Pleased to meet you."

Mary: How do you do.
Ken: Mary works for ...
Ken: Peter, I'd like you to meet Mary.

In informal situations, especially in North America, introductions are also made simply saying: "This is (name)." It is also common to just say "Hi" or "Hello" as a response in this informal setting.
Ken: Peter, this is Mary.
Peter: How do you do?
Mary: Pleased to meet you.
Ken: Mary works for ...
It is also quite common to shake hands when you are introduced. After the initial introduction, hand shaking generally takes place in more formal, business situations. Otherwise, people just say "Hi."
