Thanks, Patrick and good morning, everyone. Sales in the quarter were $978.4 million, which represented a local currency increase of 10%. On a U.S. dollar basis, sales increased 6% as currency reduced sales growth by 4%. We estimate that the impact of reduced sales in Russia, Ukraine, due to the war was a headwind of about 1% to sales growth. On Slide number 4, we show sales growth by region. Local currency sales increased 12% in the Americas, 4% in Europe and 14% in Asia-Rest of the World. local currency sales increased 14% in China in the quarter.
On Slide number 5, we show sales growth by region for the first half of the year. Local currency sales grew 12% for the first six months with 14% growth in the Americas, 7% in Europe and 15% in Asia-Rest of the World. Local currency sales increased 15% in China on a year-to-date basis. On Slide number 6, we summarized local currency sales growth by product area. For the quarter, laboratory sales increased 13%, industrial increased 9% with core industrial up 11% and product inspection up 5%. Food retail grew 3% in the quarter.
The next slide shows local currency sales growth by product area for the first half. Laboratory sales increased 15%, industrial increased 10%, including 12% growth in core industrial and product inspection, up 7%. Food retail declined 6%. Let me now move to the rest of the P&L, which is summarized on Slide number 8. Gross margin in the quarter was 58.4%, an increase of 30 basis points. We benefited from strong pricing and volume growth, which was offset in part by higher material costs. R&D amounted to $44 million in the quarter, which is an 8% increase in local currency over the prior period, reflecting increased project activity.
SG&A, amounted to $242.2 million, a 6% increase in local currency over the prior year, which includes increased investments in sales and marketing. Adjusted operating profit amounted to $285.4 million in the quarter, a 12% increase. The increase reflects strong sales growth combined with good execution. Currency was a 3% headwind to operating profit growth. Adjusted operating margin was 29.2%, which represents an increase of 160 basis points over the prior year. On a currency neutral basis, adjusted operating margins increased 120 basis points.
A couple of final comments on the P&L. Amortization amounted to $16.4 million in the quarter, interest expense was $12.8 million in the quarter. Other income in the quarter amounted to $2.2 million, primarily reflecting non-service related pension income. Our effective tax rate was 19% in the quarter. This rate is before discrete items and adjusting for the timing of stock option exercises in the quarter. Fully diluted shares amounted to 22.8 million in the quarter, which is a 3% decline from the prior year. Adjusted EPS for the quarter was $9.39, a 16% increase over the prior year or 20% increase excluding unfavorable foreign currency. We are very pleased with this adjusted EPS growth, especially given that adjusted EPS was up more than 50% in the second quarter of last year.
On a reported basis in the quarter, EPS was $9.29 as compared to $7.85 in the prior year. Reported EPS includes $0.22 of purchased intangible amortization, $0.06 of restructuring and an $0.18 benefit due to the difference between our quarterly and annual tax rate due to the timing of stock option exercises. The next slide illustrates our year-to-date results. Local currency sales grew 12% for the six-month period. Adjusted operating income increased 13% or 16% excluding unfavorable foreign currency and our operating margin expanded a 110 basis points. Adjusted EPS grew 18% on a year-to-date basis or 21% excluding unfavorable currency.
That covers the P&L and let me now comment on cash flow. In the quarter, adjusted free cash flow amounted to $208.2 million. We continue to make nice improvements on DSO, which declined two days to 34 days as compared to the prior year. Aiteo [Phonetics] came in at 3.8 times. Year-to-date, adjusted free cash flow was $283.7 million.
Let me now turn to guidance. Forecasting continues to be challenging given dynamic market conditions. Our forecast remains on fact -- our focus remains on factors we can control, namely, successful execution of our growth and margin initiatives.
Let me make some general comments on the full year before covering the specifics. Well, there is more macro noise in the environment today as compared three months ago. We continue to feel good about our business. Customer demand is solid, and we are executing on our growth initiatives very well. We remain cautious about challenges in the supply chain, but to date have been able to navigate them well. Second, we are facing greater foreign exchange headwinds to our earnings growth as compared to three months ago. Specifically, we now estimate that foreign currency will be a headwind to adjusted EPS growth in the quarter of approximately 6% and would expect a similar headwind in the fourth quarter as well. At the time of our last earnings call, the headwind to earnings growth in the second half of the year was in the range of 3% to 4%. What this means for the full year as we now expect currency to be a headwind to adjusted EPS of approximately 4.5% as compared to 3.5% the last time we spoke. At the midpoint of our guidance, we now expect adjusted operating profit margin to increase approximately 140 basis points on a currency neutral basis, reflecting higher volume growth and good execution on our margin initiatives, including currency, reported operating margin, profit margin will be slightly higher. Finally, as you think through our sales guidance, keep in mind our sales growth will be reduced by approximately 1% for the remainder of the year due to sales in Russia.
Now let me cover the specifics. For the full year 2022, we now expect local currency sales growth to be in the range of 9% to 10%. This compares to previous guidance of 8%. We are increasing our full-year sales guidance for our strong year-to-date results and a better outlook for the second half. We expect full year adjusted EPS to be in the range of $38.85 to $39.05, which is a growth rate of 14% to 15% and a growth rate of approximately 19% excluding currency. For the third quarter, based on market conditions today, we expect local currency sales growth of approximately 8% and expect adjusted EPS to be in a range of $9.75 to $9.85, a growth rate of 12% to 13% and a growth of 18% to 19% excluding currency.
Some final details on guidance. With respect to the impact of currency on sales growth, we expect currency to decrease sales growth by approximately 4.5% for the full year and decrease sales about 6% in Q3. In terms of cash flow, we expect -- we continue to expect full year cash flow in the $855 million range and expect to repurchase approximately $1.1 billion in shares in 2022. We expect a net debt to EBITDA leverage ratio of approximately 1.5 times. That is it from my side, and I'll now turn it back to Patrick.
