POWER OF ATTORNEY

Know all by these presents that the undersigned hereby constitutes and
appoints each of Daniel Char, Michael Lanieri and Meghan Shevlin as the
undersigned's true and lawful attorney-in-fact to:

(1) execute for and on behalf of the undersigned, in the undersigned's capacity
as a beneficial owner of Quanterix Corporation (the "Company"), Forms 3, 4,
and 5 in accordance with Section 16(a) of the Securities Exchange Act of 1934
and the rules thereunder and Schedules 13D and 13G in accordance with Section
13 of the Securities Exchange Act of 1934 and the rules thereunder;

(2) do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete and execute any such Form 3, 4, or 5
or Schedules 13D or 13G, complete and execute any amendment or amendments
thereto, and timely file such form with the U.S. Securities and Exchange
Commission (the "SEC") and any securities exchange or similar authority; and

(3) take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of
the undersigned pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may approve
in such attorney-in-fact's discretion.

The undersigned hereby grants to each attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes as the undersigned
might or could do if personally present, with full power of substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact, or
such attorney-in-fact's substitute or substitutes, shall lawfully do or cause
to be done by virtue of this power of attorney and the rights and powers
herein granted. The undersigned also ratifies hereby any action previously
taken by each attorney-in-fact that would have been authorized by this power
of attorney if it had been in effect at the time such action was taken. The
undersigned acknowledges that each foregoing attorney-in-fact, in serving in
such capacity at the request of the undersigned, is not assuming, nor is the
Company assuming, any of the undersigned's responsibilities to comply with
Sections 13 and 16 of the Securities Exchange Act of 1934.

This Power of Attorney supersedes all previously granted powers of attorney
relating to the execution of the forms and schedules described in paragraph (1)
above. This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 and Schedules 13D
and 13G with respect to the undersigned's holdings of and transactions in
securities issued by the Company, unless earlier revoked by the undersigned
in a signed writing delivered to each foregoing attorney-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 16th day of June 2026.
